示例

下面的示例显示集合OleDbError中的OleDbErrorCollection每个。The following example displays each OleDbError within the OleDbErrorCollection collection.

public void DisplayOleDbErrorCollection(OleDbException exception) 
{
   for (int i=0; i < exception.Errors.Count; i++)
   {
      MessageBox.Show("Index #" + i + "\n" +
             "Message: " + exception.Errors[i].Message + "\n" +
             "Native: " + exception.Errors[i].NativeError.ToString() + "\n" +
             "Source: " + exception.Errors[i].Source + "\n" +
             "SQL: " + exception.Errors[i].SQLState + "\n");
   }
}
Public Sub DisplayOleDbErrorCollection(exception As OleDbException)
    Dim i As Integer

    For i = 0 To exception.Errors.Count - 1
        MessageBox.Show("Index #" + i.ToString() + ControlChars.Cr _
           + "Message: " + exception.Errors(i).Message + ControlChars.Cr _
           + "Native: " + exception.Errors(i).NativeError.ToString() + ControlChars.Cr _
           + "Source: " + exception.Errors(i).Source + ControlChars.Cr _
           + "SQL: " + exception.Errors(i).SQLState + ControlChars.Cr)
    Next i
End Sub

注解

此类由OleDbException创建, 用于收集OleDbError类的实例。This class is created by OleDbException to collect instances of the OleDbError class. OleDbErrorCollection始终包含至少一个OleDbError类的实例。OleDbErrorCollection always contains at least one instance of the OleDbError class.

属性

Count Count Count Count

获取集合中错误的数目。Gets the number of errors in the collection.

Item[Int32] Item[Int32] Item[Int32] Item[Int32]

获取位于指定索引处的错误。Gets the error at the specified index.

方法
