从数据表中删除包含值的行

Question

I want to have a row with column CtryCode equal to "MM" deleted. Is this logic above doesn't do it?

if (dataTableCopy.Rows[index]["CtryCode"].ToString().Trim().ToUpper().Contains("MM"))
{
    response.DataTable.Rows.RemoveAt(index + offset--);
}

Breakpoint is not hitting the response statement above and I could see MM row after the execution of this, strange? Please help.

Answer 1

To delete row that contains value try this

DataRow[] result = dt2.Select("CtryCode = 'mm'");
foreach (DataRow row in result)
{
    if (row["CtryCode"].ToString().Trim().ToUpper().Contains("MM"))
    dt2.Rows.Remove(row);
}

Answer 2

If you know the index of that row, You can delete the row like this,

for(int i=0;i<dataTableCopy.Rows.Count-1;i++)
   {        
        if (dataTableCopy.Rows[i]["CtryCode"].ToString().Trim().ToUpper().Contains("MM"))
    {
         dataTableCopy.Rows[i].Delete();
    }
  }

Please find the code:

int id=98;
DataTable dt = new DataTable();
foreach (DataRow row in dt.Rows)
{
    if(row["Id"].ToString().Trim().Contains(id.ToString()))
        dt.Rows.Remove(row);
}
