Check if DataRow exists by column name in c#?

if (drMyRow.Table.Columns["ColNameToCheck"] != null)
{
   doSomethingUseful;
{
else { return; }

Although the DataRow does not have a Columns property, it does have a Table that the column can be checked for.

You can use the DataColumnCollection of Your datatable to check if the column is in the collection.

Something like:

DataColumnCollection Columns = dtItems.Columns;

if (Columns.Contains(ColNameToCheck))
{
  row["ColNameToCheck"] = "Checked";
}

You should try

if (row.Table.Columns.Contains("US_OTHERFRIEND"))

I don't believe that row has a columns property itself.
