c#DataGridView显示不了数据

Question

代码：
SqlConnection objConn = new SqlConnection();
SqlCommand objComm = new SqlCommand();
objConn.ConnectionString = @"Data Source=PC-201401220416\SQL2008;Initial Catalog=XSCJ;Integrated Security=True";
objComm.CommandText = "Select XH as 学号,XM as 姓名,XB as 性别,CSRQ as 出生时间,ZY as 专业,ZXF as 总学分 From XSB";
objComm.Connection = objConn;
objDa.SelectCommand = objComm;
SqlCommandBuilder builder = new SqlCommandBuilder(objDa);
objDa.Fill(objDs,"xs");
objXSTable = objDs.Tables[0];
DataGridView1.DataSource = objDs.Tables["XSB"];

运行之后显示不出数据 求问

Answer 1

是否报错了，如果是贴报错截图

是否外部用了try catch，如果用了，去掉再运行

把连接字符串改一下试试PC-201401220416\SQL2008改成.\sqlexpress

Answer 2

DataGridView1.DataSource = objDs.Tables["xs"];
