Why does compiling this code result in a syntax error?

I wrote the following code but i am getting th开发者_运维技巧e error as i mentioned can any one tell

protected void btnGenerate_Click(object sender, EventArgs e)
{
    DataRow[] dRow;
    DataTable dt = new DataTable();
    foreach (GridViewRow grRow in grdACH.Rows)
    {
        CheckBox chkItem = (CheckBox)grRow.FindControl("checkRec");
        if (chkItem.Checked)
        {
            chkItm = true;
            chkcnt++;
            strBankTypeID = ((Label)grRow.FindControl("lblBankType")).Text.ToString();
            strBnkArray.Append(strBankTypeID);
            strBnkArray.Append(",");
        }
    }
    oEmpDeposits.getEmpDepositDetails(out local_ds, strFedTaxId, PayperiodNumber, PayrollYear, strPayFreqType);

for (int i = 0; i < local_ds.Tables[0].Rows.Count; i++)
    {
        string strTrim = strBnkArray.ToString().TrimEnd(',');
        strTrim = "BankAccountTypeID='" + strTrim[i] + "'";
        if (strTrim.Contains("BankAccountTypeID=',"))
        {
            strTrim = "BankAccountTypeID='" + strTrim[i] + "'";
        }

        dRow = local_ds.Tables[0].Select(strTrim);
    }
}

---

The syntax error comes from this statement:

dRow = local_ds.Tables[0].Select(strBnkArray.ToString().TrimEnd(','));

There is something wrong with the expression you are trying to use.

That expression is made up from this:

strBnkArray.ToString().TrimEnd(',')

Check what that is and you find the answer. Like this perhaps:

string mySelectStatement = strBnkArray.ToString().TrimEnd(',');
dRow = local_ds.Tables[0].Select(mySelectStatement);

WHy don't you use ArrayList instead of String array. So that it will be easy to manipulate

Sample

if (chkItem.Checked)
{
  chkItm = true;
  chkcnt++;
  strBankTypeID += ((Label)grRow.FindControl("lblBankType")).Text.ToString(); 
  ArrayList lstArray=new ArrayList();
  lstArray.Add(strBankTypeID);
}

Later

 oEmpDeposits.getEmpDepositDetails(out local_ds, strFedTaxId, PayperiodNumber, PayrollYear, strPayFreqType);

    for (int i = 0; i < lstArray.Count; i++)
    {
        //string strTrim = strBnkArray.ToString().TrimEnd(',');
        strBankAccntType = "BankAccountTypeID='" + lstArray[i].ToString() + "'";
        dRow = local_ds.Tables[0].Select(strBankAccntType);
    }
