several test cases were executed in order to treat the particularities of a sequence of CSV characters; in this publication, is considered stable, it is implemented in productive environments with large scale of data generated or consumed in CSV daily. 4 | 5 | Specifications: This 'CsvSerializer' class enjoy best pratices of Design Patterns result in a powerful CSV serialization and deserialization functionality, giving to Developer other data sctructure options like [DataTable](https://docs.microsoft.com/en-us/dotnet/api/system.data.datatable) object or a custom C# Plain Old CLR Object (Entity class) with capacity to define column name and order exihbition. 6 | Both methods 'Serialize' and 'Deserialize' contains on important argument named "csvSeparator" to gives flexible generation of CSV. 7 | 8 | Bellow are examples of using the 'CsvSerializer': 9 | 10 | ## 1) Serialize 11 | 12 | #### 1.1) Using a POCO (Plain Old CLR Objects) class, with native .NET [DataMemberAtribute](https://docs.microsoft.com/en-us/dotnet/api/system.runtime.serialization.datamemberattribute) (attribute is not mandatory): 13 | ```cs 14 | public class ExampleModel 15 | { 16 | [DataMember(Name = "My Property 1", Order = 4)] 17 | public string MyProperty1 { get; set; } 18 | 19 | [DataMember(Name = "My Property 2", Order = 1)] 20 | public string MyProperty2 { get; set; } 21 | 22 | [DataMember(Name = "Any Property", Order = 3)] 23 | public string AnyProperty { get; set; } 24 | 25 | [DataMember(Name = "Property comments change order", Order = 6)] 26 | public string PropertyWithChangeOrder { get; set; } 27 | 28 | [DataMember(Name = "Some Property", Order = 2)] 29 | public string SomeProperty { get; set; } 30 | 31 | [DataMember(Name = "Capacity Property", Order = 5)] 32 | public string CapacityProperty { get; set; } 33 | } 34 | ``` 35 | 36 | #### 1.2) Create a collection based on Entity class above: 37 | ```cs 38 | List list = new List(); 39 | 40 | list.Add(new ExampleModel() 41 | { 42 | AnyProperty = "any 1", 43 | CapacityProperty = "20", 44 | MyProperty1 = "my 1", 45 | MyProperty2 = "my 2", 46 | PropertyWithChangeOrder = "Comments to change and or texts...", 47 | SomeProperty = "some 1" 48 | }); 49 | list.Add(new ExampleModel() 50 | { 51 | AnyProperty = "any yna", 52 | CapacityProperty = "45", 53 | MyProperty1 = "11 my", 54 | MyProperty2 = "22 my", 55 | PropertyWithChangeOrder = "Another comment to change contents!", 56 | SomeProperty = "2 some 1" 57 | }); 58 | list.Add(new ExampleModel() 59 | { 60 | AnyProperty = @"\/any yna\/", 61 | CapacityProperty = "57", 62 | MyProperty1 = "1my1", 63 | MyProperty2 = "2my2", 64 | PropertyWithChangeOrder = "Texts with comments to rich all tests", 65 | SomeProperty = "some3" 66 | }); 67 | ``` 68 | 69 | #### 1.3) Execute Serialize method, and *Voilà*! 70 | ```cs 71 | string csvSerialized = CsvSerializer.Serialize(';', list); 72 | ``` 73 | 74 | #### 1.4) This is the result of the string bulk: 75 | ```csv 76 | My Property 2;Some Property;Any Property;My Property 1;Capacity Property;Property comments change order; 77 | 78 | my 2;some 1;any 1;my 1;20;Comments to change and or texts...; 79 | 80 | 22 my;2 some 1;any yna;11 my;45;Another comment to change contents!; 81 | 82 | 2my2;some3;\/any yna\/;1my1;57;Texts with comments to rich all tests; 83 | ``` 84 | 85 | #### 1.5) Pear attention: if you want to save '*.csv*' file, remeber to use Encoding UTF8, according [CSV specifications](https://en.wikipedia.org/wiki/Comma-separated_values): 86 | ```cs 87 | File.WriteAllText(@"\\path\to\save\file.csv", csvSerialized, Encoding.UTF8); 88 | ``` 89 | ---------------------------- 90 | 91 | ## 2) Deserialize 92 | 93 | #### 2.1) The developer may consume any '*.csv*' file by sugestted instruction: 94 | ```cs 95 | string csvToDeserialize = File.ReadAllText(@"\\path\to\read\file.csv"); 96 | ``` 97 | 98 | #### 2.2) And, if dont know the data column arrange, may populate a DataTable objet: 99 | ```cs 100 | DataTable dtDeserialized = CsvSerializer.Deserialize(';', csvToDeserialize); 101 | ``` 102 | 103 | #### 2.2) Or populate a collection of Entity class (like array or list): 104 | ```cs 105 | ExampleModel[] arrayCollection = CsvSerializer.Deserialize(';', csvToDeserialize).ToArray(); 106 | List listCollection = CsvSerializer.Deserialize(';', csvToDeserialize).ToList(); 107 | ``` 108 | ---------------------- 109 | ## License 110 | 111 | [View MIT license](https://github.com/antonio-leonardo/CsvSerializer/blob/master/LICENSE) 112 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | ## Ignore Visual Studio temporary files, build results, and 2 | ## files generated by popular Visual Studio add-ons. 3 | ## 4 | ## Get latest from https://github.com/github/gitignore/blob/master/VisualStudio.gitignore 5 | 6 | # User-specific files 7 | *.rsuser 8 | *.suo 9 | *.user 10 | *.userosscache 11 | *.sln.docstates 12 | 13 | # User-specific files (MonoDevelop/Xamarin Studio) 14 | *.userprefs 15 | 16 | # Build results 17 | [Dd]ebug/ 18 | [Dd]ebugPublic/ 19 | [Rr]elease/ 20 | [Rr]eleases/ 21 | x64/ 22 | x86/ 23 | [Aa][Rr][Mm]/ 24 | [Aa][Rr][Mm]64/ 25 | bld/ 26 | [Bb]in/ 27 | [Oo]bj/ 28 | [Ll]og/ 29 | 30 | # Visual Studio 2015/2017 cache/options directory 31 | .vs/ 32 | # Uncomment if you have tasks that create the project's static files in wwwroot 33 | #wwwroot/ 34 | 35 | # Visual Studio 2017 auto generated files 36 | Generated\ Files/ 37 | 38 | # MSTest test Results 39 | [Tt]est[Rr]esult*/ 40 | [Bb]uild[Ll]og.* 41 | 42 | # NUNIT 43 | *.VisualState.xml 44 | TestResult.xml 45 | 46 | # Build Results of an ATL Project 47 | [Dd]ebugPS/ 48 | [Rr]eleasePS/ 49 | dlldata.c 50 | 51 | # Benchmark Results 52 | BenchmarkDotNet.Artifacts/ 53 | 54 | # .NET Core 55 | project.lock.json 56 | project.fragment.lock.json 57 | artifacts/ 58 | 59 | # StyleCop 60 | StyleCopReport.xml 61 | 62 | # Files built by Visual Studio 63 | *_i.c 64 | *_p.c 65 | *_h.h 66 | *.ilk 67 | *.meta 68 | *.obj 69 | *.iobj 70 | *.pch 71 | *.pdb 72 | *.ipdb 73 | *.pgc 74 | *.pgd 75 | *.rsp 76 | *.sbr 77 | *.tlb 78 | *.tli 79 | *.tlh 80 | *.tmp 81 | *.tmp_proj 82 | *_wpftmp.csproj 83 | *.log 84 | *.vspscc 85 | *.vssscc 86 | .builds 87 | *.pidb 88 | *.svclog 89 | *.scc 90 | 91 | # Chutzpah Test files 92 | _Chutzpah* 93 | 94 | # Visual C++ cache files 95 | ipch/ 96 | *.aps 97 | *.ncb 98 | *.opendb 99 | *.opensdf 100 | *.sdf 101 | *.cachefile 102 | *.VC.db 103 | *.VC.VC.opendb 104 | 105 | # Visual Studio profiler 106 | *.psess 107 | *.vsp 108 | *.vspx 109 | *.sap 110 | 111 | # Visual Studio Trace Files 112 | *.e2e 113 | 114 | # TFS 2012 Local Workspace 115 | $tf/ 116 | 117 | # Guidance Automation Toolkit 118 | *.gpState 119 | 120 | # ReSharper is a .NET coding add-in 121 | _ReSharper*/ 122 | *.[Rr]e[Ss]harper 123 | *.DotSettings.user 124 | 125 | # JustCode is a .NET coding add-in 126 | .JustCode 127 | 128 | # TeamCity is a build add-in 129 | _TeamCity* 130 | 131 | # DotCover is a Code Coverage Tool 132 | *.dotCover 133 | 134 | # AxoCover is a Code Coverage Tool 135 | .axoCover/* 136 | !.axoCover/settings.json 137 | 138 | # Visual Studio code coverage results 139 | *.coverage 140 | *.coveragexml 141 | 142 | # NCrunch 143 | _NCrunch_* 144 | .*crunch*.local.xml 145 | nCrunchTemp_* 146 | 147 | # MightyMoose 148 | *.mm.* 149 | AutoTest.Net/ 150 | 151 | # Web workbench (sass) 152 | .sass-cache/ 153 | 154 | # Installshield output folder 155 | [Ee]xpress/ 156 | 157 | # DocProject is a documentation generator add-in 158 | DocProject/buildhelp/ 159 | DocProject/Help/*.HxT 160 | DocProject/Help/*.HxC 161 | DocProject/Help/*.hhc 162 | DocProject/Help/*.hhk 163 | DocProject/Help/*.hhp 164 | DocProject/Help/Html2 165 | DocProject/Help/html 166 | 167 | # Click-Once directory 168 | publish/ 169 | 170 | # Publish Web Output 171 | *.[Pp]ublish.xml 172 | *.azurePubxml 173 | # Note: Comment the next line if you want to checkin your web deploy settings, 174 | # but database connection strings (with potential passwords) will be unencrypted 175 | *.pubxml 176 | *.publishproj 177 | 178 | # Microsoft Azure Web App publish settings.
