DataTable序列化

 

免去复杂的引用 一步到位

DataTable dt = new DataTable();
dt = db.getDataSet(sql).Tables[0];

if (dt == null || dt.Rows.Count < 1)
{
　　// 如果DataTable为空
}
string strjson = "[";
for (int i = 0; i < dt.Rows.Count; i++)
{
strjson += "{\"CODE\"" + ":" + "\"" + dt.Rows[i].ItemArray[0] + "\"" + "," + "\"NAME\"" + ":" + "\"" + dt.Rows[i].ItemArray[1] + "\"" + ","
+ "\"CODE\"" +":"+ "\""+ dt.Rows[i].ItemArray[2] + "\"" + "," + "\"CODE\"" + ":" + "\""+ dt.Rows[i].ItemArray[3] + "\"" + "," + "\"CODE\"" + ":" + "\""+ dt.Rows[i].ItemArray[4] + "\"},";
}
strjson = strjson.TrimEnd(',');
strjson += "]";

 

strjson 出来便是JSON的格式  

Key可以填自己的字段
