这是我写的触发代码,现在显示的是全部data里面的内容,我只需要一部分data里面的,比如说L值,K值,而不要全部显示,求请教
string url = "xxx";
string jsonParas = "workorder_id=" + 4 + "&" + "product_id=" + 1 + "&" + "process_no=" + 10 + "&" + "process_no_order=" + 1 + "&";
string getJson = HttpUitls.Post(url,jsonParas,"POST");
DataTable x = JsonToDataTable(getJson);
dataGridView1.DataSource = x;
dataGridView1.Rows[0].Selected = false;
JsonToDataTable的方法代码
public static DataTable JsonToDataTable(string strJson)
{
//转换json格式
strJson = strJson.Replace(",\"", "*\"").Replace("\":", "\"#").ToString();
//取出表名
var rg = new Regex(@"(?<={)[^:]+(?=:\[)", RegexOptions.IgnoreCase);
string strName = rg.Match(strJson).Value;
DataTable tb = null;
//去除表名
strJson = strJson.Substring(strJson.IndexOf("[") + 1);
strJson = strJson.Substring(0, strJson.IndexOf("]"));
//获取数据
rg = new Regex(@"(?<={)[^}]+(?=})");
MatchCollection mc = rg.Matches(strJson);
for (int i = 0; i < mc.Count; i++)
{
string strRow = mc[i].Value;
string[] strRows = strRow.Split('*');
//创建表
if (tb == null)
{
tb = new DataTable();
tb.TableName = strName;
foreach (string str in strRows)
{
var dc = new DataColumn();
string[] strCell = str.Split('#');
if (strCell[0].Substring(0, 1) == "\"")
{
int a = strCell[0].Length;
dc.ColumnName = strCell[0].Substring(1, a - 2);
}
else
{
dc.ColumnName = strCell[0];
}
tb.Columns.Add(dc);
}
tb.AcceptChanges();
}
//增加内容
DataRow dr = tb.NewRow();
for (int r = 0; r < strRows.Length; r++)
{
dr[r] = strRows[r].Split('#')[1].Trim().Replace(",", ",").Replace(":", ":").Replace("\"", "");
}
tb.Rows.Add(dr);
tb.AcceptChanges();
}
return tb;
}
