如何 DataTable格式转换json格式

1.序列化啊  宝贝！！

public string DataTableToJsonWithJsonNet(DataTable table)
{
   string jsonString=string.Empty;
   jsonString = JsonConvert.SerializeObject(table);
   return jsonString;
}

　　

额

2.还有一个恶心点的方法

public string DataTableToJson(DataTable table)
{
var JsonString = new StringBuilder();
if (table.Rows.Count > )
{
JsonString.Append("[");
for (int i = ; i < table.Rows.Count; i++)
{
JsonString.Append("{");
for (int j = ; j < table.Columns.Count; j++)
{
if (j < table.Columns.Count - )
{
JsonString.Append("\"" + table.Columns[j].ColumnName.ToString()
+ "\":" + "\"" + table.Rows[i][j].ToString() + "\",");
}
else if (j == table.Columns.Count - )
{
JsonString.Append("\"" + table.Columns[j].ColumnName.ToString()
+ "\":" + "\"" + table.Rows[i][j].ToString() + "\"");
}
}
if (i == table.Rows.Count - )
{
JsonString.Append("}");
}
else
{
JsonString.Append("},");
}
}
JsonString.Append("]");
}
return JsonString.ToString();
}
