GetErrors Method

DataTable.GetErrors Method

Gets an array of DataRow objects that contain errors.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

public DataRow[] GetErrors ()
public DataRow[] GetErrors ()
public function GetErrors () : DataRow[]
Not applicable.

Return Value

An array of DataRow objects that have errors.

Invoke GetErrors after invoking the DataSet class's GetChanges method. Also, be sure you do not invoke AcceptChanges on the DataTable until after you have resolved all errors, and have re-submitted the DataSet for updating.

The following example uses the GetErrors method to return an array of DataRow objects that have errors.

private void PrintAllErrs(DataSet dataSet)
{
    DataRow[] rowsInError; 
  
    foreach(DataTable table in dataSet.Tables)
    {
        // Test if the table has errors. If not, skip it.
        if(table.HasErrors)
        {
            // Get an array of all rows with errors.
            rowsInError = table.GetErrors();
            // Print the error of each column in each row.
            for(int i = 0; i < rowsInError.Length; i++)
            {
                foreach(DataColumn column in table.Columns)
                {
                    Console.WriteLine(column.ColumnName + " " + 
                        rowsInError[i].GetColumnError(column));
                }
                // Clear the row errors
                rowsInError[i].ClearErrors();
            }
        }
    }
}
