Cannot implicitly convert type 'int' to 'string'

Question

My code:

public void FillMaxBankCode()
{
    try
    {
        DataSet ds = new DataSet();
        ds = bol.SelectMaxBankCode();
        string j = ds.Tables[0].         


        

Answer 1

If you want to ensure that the value is an integer before assigning it I suggest you use TryParse

// check if the table and row exists
if (ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0)
{
    string j = ds.Tables[0].Rows[0].ToString();
    int value = 0;
    if (int.TryParse(j, out value))
        txtbankid.Text = value.ToString();
}
