在进行数据传递的时候,有时我们需要通过Ajax的方式或者其他的方式传递一个数据列表,可以将DataTable或者其他形式的数据列表转换为JSON的格式,通过Ajax实体的形式进行传递. 比如说: /// <summary> /// DataTable 转换为Json /// </summary> /// <param name="dt">datatable</param> /// <returns></returns&g…

//第一种:使用StringBuilder  public string DataTableToJson(DataTable table) { var JsonString = new StringBuilder(); ) { JsonString.Append("["); ; i < table.Rows.Count; i++) { JsonString.Append("{"); ; j < table.Columns.Count; j++) { )…

private string DataTableToJson(DataTable dt) { string Json = ""; Json = Json + "["; foreach (DataRow dr in dt.Rows) { Json = Json + "{"; foreach (DataColumn dc in dt.Columns) { Json = Json + "\"" + dc.ColumnNam…

最后的格式为:[{},{},...] StringBuilder DataTableToJSON(DataTable dt) { string columnName; StringBuilder builder = new StringBuilder(); if (dt != null && dt.Rows.Count >= 1) { builder.Append("["); for (int i = 0; i < dt.Rows.Count; i++) {…
