 今天总结一下关于DataTable,XML转JSON的方法:

首先需要引入命名空间: using Newtonsoft.Json 1 public string DataTableToJsonWithStringBuilder(DataTable table)

 2     {  3         var jsonString = new StringBuilder();  4         if (table.Rows.Count > 0)  5         {  6               jsonString.Append("[");  7             for (int i = 0; i < table.Rows.Count; i++)  8             {  9                 jsonString.Append("{"); 10                 for (int j = 0; j < table.Columns.Count; j++) 11                 { 12                     if (j < table.Columns.Count - 1) 13                     { 14                         jsonString.Append(""" + table.Columns[j].ColumnName.ToString() 15                      + "":" + """ 16                      + table.Rows[i][j].ToString() + "","); 17                     } 18                     else if (j == table.Columns.Count - 1) 19                     { 20                         jsonString.Append(""" + table.Columns[j].ColumnName.ToString() 21                      + "":" + """ 22                      + table.Rows[i][j].ToString() + """); 23                     } 24                 } 25                 if (i == table.Rows.Count - 1) 26                 { 27                     jsonString.Append("}"); 28                 } 29                 else 30                 { 31                     jsonString.Append("},"); 32                 } 33             } 34               jsonString.Append("]"); 35         } 36         return jsonString.ToString(); 37     }

调用:

var xmlToJson = DataTableToJsonWithStringBuilder(newdt);// datatable转json数组

//XML转JSON
var xmlToJson1 = JsonConvert.SerializeXmlNode(child, Newtonsoft.Json.Formatting.None, true);
