I have written the following code:
using System.Data;
using System.Data.SqlClient;
private void Form1_Load(object sender, EventArgs e)
{//create persistent connection
SqlConnection myConn = new SqlConnection();
DialogResult dr;
dr = dlgOpen.ShowDialog();
if (dr == DialogResult.OK)
{ string strFile = dlgOpen.FileName;
myConn.ConnectionString = "Provider=" +
"Microsoft SQL Server=" + strFile +
";";
//open connection
myConn.Open();
//create command
SqlCommand myCMD = new SqlCommand();
myCMD.CommandText = "SELECT CustomerID, " +
"ContactTitle, CompanyName, ContactName " +
"FROM Customers";
//linking command to connection
.................
}
}
I get the following errors:
Compiler Error CS0433 The type 'System.Data.SqlClient.SqlConnection' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Data.dll' and 'c:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PublicAssemblies\System.Data.SqlClient.dll'

I would be grateful if somebody could point out what I am doing wrong, and how I can rectify the mistakes.
