Json转DataTable

开发语言 C#

开发环境 .net framework 4.7.2

Newtonsoft.Json 版本 6.0

准备好Json数据,Json数据如下:

{"columns":["列1","列2"],"rows":{"0":{"列1":"1","列2":"2"},"2":{"列1":"11","列2":"22"}}}

Json格式化效果如下:

下面是服务器端代码,方法可以直接复制

 1       /// <summary>
 2         /// 根据传入的JSON数据,生成表格
 3         /// </summary>
 4         /// <param name="FiledsNames">列集合</param>
 5         /// <param name="Rows">行集合</param>
 6         /// <returns></returns>
 7         public static DataTable GetDataTableByJson(JToken FiledsNames, JToken Rows)
 8         {
 9             DataTable result = new DataTable();
10             //增加列
11             foreach (JToken i in FiledsNames)
12             {
13                 DataColumn tempColumn = new DataColumn();
14                 tempColumn.ColumnName = i.ToString();
15                 tempColumn.DataType = i.GetType();
16                 result.Columns.Add(tempColumn);
17             }
18 
19             //增加行
20             foreach (JToken i in Rows)
21             {
22                 foreach (JToken l in i)
23                 {
24                     DataRow tempRow = result.NewRow();
25                     List<object> rowsList = new List<object>();
26                     foreach (JToken z2 in FiledsNames)
27                     {
28                         JToken tempRowValue = l[z2.ToString()];
29                         rowsList.Add(tempRowValue);
30                     }
31                     tempRow.ItemArray = rowsList.ToArray();
32                     result.Rows.Add(tempRow);
33                 }
34             }
35             return result;
