Unable to cast object of type 'System.Int32' to type 'System.String' in DataReader.GetString()

Question

I was trying to add data from a database to acombobox.

        try
        {
            SqlCeCommand com = new SqlCeCommand(\"select * from Category_Master\

Ok OK. Its solved....

Here is the code..

        try
        {
            SqlCeCommand com = new SqlCeCommand("select CategoryName from Category_Master", con);
            SqlCeDataReader dr = com.ExecuteReader();
            while(dr.Read()){
                string name = dr.GetString(0);
                cmbProductCategory.Items.Add(name);
            }
        }
        catch(Exception ex)
        {
            System.Windows.Forms.MessageBox.Show(ex.Message, System.Windows.Forms.Application.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error);
        }

I changed the sqlcommand to a single value and changed column number for dr.getstring() to 0.. it worked. Thank you guys for the help.. I expect more because i am only half way in my project..
