C resolves Json to DateTable

This article shows an example of how C# resolves Json to DateTable. Share to everybody for everybody reference. Specific implementation methods are as follows:

#region  will  Json  Parsed into  DateTable ///  

///  will  Json  Parsed into  DateTable .  

/// Json  Data formats such as : ///

 {table:[{column1:1,column2:2,column3:3},{column1:1,column2:2,column3:3}]} 

///  

/// To parse the  Json  string 

 ///  return  DateTable public DataTable JsonToDataTable(string strJson) 

{ 

// 

 Take out the name of the table  var rg = new Regex(@(?<={)[^:]+(?=:[), RegexOptions.IgnoreCase);

 string strName = rg.Match(strJson).Value; DataTable tb = null;

 //  Remove the name of the table  strJson = strJson.Substring(strJson.IndexOf([) + 1);

 strJson = strJson.Substring(0, strJson.IndexOf(]));

 //  To get the data 

 rg = new Regex(@(?<={)[^}]+(?=})); MatchCollection mc = rg.Matches(strJson);

 for (int i = 0; i < mc.Count; i++) { 

string strRow = mc[i].Value; string[] strRows = strRow.Split(','); 

//  Create a table  if (tb == null) { tb = new DataTable();

 tb.TableName = strName; foreach (string str in strRows) 

{ var dc = new DataColumn(); 

string[] strCell = str.Split(':'); 

dc.ColumnName = strCell[0].Replace(, );

 tb.Columns.Add(dc); }

 tb.AcceptChanges();

 } //  Increase the content of  DataRow dr = tb.NewRow(); 

for (int j = 0; j < strRows.Length; j++) 

{ dr[j] = strRows[j].Split(':')[1].Replace(, 

); 

} tb.Rows.Add(dr); 

tb.AcceptChanges();

 } 

return tb; }

 #endregion

Format as follows:

{

    table: [

        {

            column1: 1, 

            column2: 2, 

            column3: 3

        }, 

        {

            column1: 1, 

            column2: 2, 

            column3: 3

        }

    ]

}

Such as:

[{Code:MetaDataId,Name:MetaDataId},{Code:MetadataCode,Name: Serial number },{Code:SolutionName,Name: The name of the }]

After formatting:

[

    {

        Code: MetaDataId, 

        Name: MetaDataId

    }, 

    {

        Code: MetadataCode, 

        Name:  Serial number 

    }, 

    {

        Code: SolutionName, 

        Name:  The name of the 

    }

]
