DataTable.GetErrors 方法

定义

获取包含错误的 DataRow 对象数组。Gets an array of DataRow objects that contain errors.

public:
 cli::array <System::Data::DataRow ^> ^ GetErrors();
public System.Data.DataRow[] GetErrors ();
member this.GetErrors : unit -> System.Data.DataRow[]
Public Function GetErrors () As DataRow()

返回

DataRow[]

包含错误的 DataRow 对象数组。An array of DataRow objects that have errors.

示例

下面的示例使用 GetErrors 方法返回 DataRow 具有错误的对象的数组。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();
            }
        }
    }
}
Private Sub PrintAllErrs(ByVal dataSet As DataSet)
    Dim rowsInError() As DataRow
    Dim table As DataTable  
    Dim i As Integer
    Dim column As DataColumn
    For Each table In dataSet.Tables
       ' Test if the table has errors. If not, skip it.
       If table.HasErrors Then
          ' Get an array of all rows with errors.
          rowsInError = table.GetErrors()
          ' Print the error of each column in each row.
          For i = 0 To rowsInError.GetUpperBound(0)
             For Each column In table.Columns
                Console.WriteLine(column.ColumnName, _
                rowsInError(i).GetColumnError(column))
             Next
             ' Clear the row errors
          rowsInError(i).ClearErrors
          Next i
       End If
    Next
End Sub

注解

返回具有 DataRow 集的 RowError 对象的列表。Returns the list of DataRow objects that have RowError set. 例如,在将 Update 设置为 ContinueUpdateOnError 的情况下调用 true 时,可能会出现错误。For example, errors can occur when calling Update with ContinueUpdateOnError set to true. 不要对 AcceptChanges 调用 DataTable,直到您解决所有错误并重新提交 DataSet 以供更新。Do not invoke AcceptChanges on the DataTable until you resolve all errors and resubmit the DataSet for updating.
