刚开始学，简单问题（c＃）

[yidewang]

private void Button1_Click(object sender, System.EventArgs e)
{

string strcon;
strcon="data source =localhost ;initial catalog= cgzx;user id =cgzxdb;password=cgzxdb";
SqlConnection conn;
conn=new SqlConnection(strcon);
SqlCommand cmd;
cmd=new SqlCommand("select * from cgml",conn);
conn.Open();
SqlDataAdapter MyDataAdapter;
MyDataAdapter=new SqlDataAdapter(cmd);
DataSet MyDataSet;
MyDataSet=new DataSet("MyDs");
MyDataAdapter.Fill(MyDataSet,"cgml");
DataGrid1.DataSource=MyDataAdapter;//这句出错不知错在那边
DataGrid1.DataBind();
}

strcon="data source =localhost ;initial catalog= cgzx;user id =cgzxdb;password=cgzxdb";
SqlConnection conn;
conn=new SqlConnection(strcon);
conn.Open();
SqlDataAdapter myCommand = new SqlDataAdapter(StrSql, conn);
DataSet ds = new DataSet();
myCommand.Fill(ds);
DataView dv = new DataView(ds.Tables["cgml"]);
DataGrid1.DataSource=dv;
DataGrid1.DataBind();

DataGrid1.DataSource=MyDataAdapter;//这句出错不知错在那边
改为DataGrid1.DataSource=MyDataSet;
