RowNotInTableException 类

定义

表示尝试在不位于 DataRow 中的 DataTable 上执行操作时引发的异常。Represents the exception that is thrown when you try to perform an operation on a DataRow that is not in a DataTable.

示例

下面的示例创建一个 DataTable 具有一个 DataColumn 和10个 DataRow 对象的。The following example creates a DataTable with one DataColumn and 10 DataRow objects. 删除行后,将 AcceptChanges 调用方法导致 RowNotInTableException 引发。After deleting a row, the AcceptChanges method is called causing the RowNotInTableException to be thrown.

private void DemonstrateRowNotInTableException()
{
    // Create a DataTable with one column and ten rows.
    DataTable table = new DataTable("NewTable");
    DataColumn column = new DataColumn("NewColumn");
    table.Columns.Add(column);

    DataRow newRow;
    for(int i = 0;i <10;i++)
    {
        newRow = table.NewRow();
        newRow["NewColumn"] = i;
        table.Rows.Add(newRow);
    }
    try
    {
        // Remove a row and invoke AcceptChanges.
        DataRow removedRow = table.Rows[9];
        removedRow.Delete();
        removedRow.AcceptChanges();
    }
    catch(System.Data.RowNotInTableException rowException)
    {
        Console.WriteLine("Row not in table");
    }
}
Private Sub DemonstrateRowNotInTableException()
    ' Create a DataTable with one column and ten rows.      
    Dim table As New DataTable("NewTable")
    Dim column As New DataColumn("NewColumn")
    table.Columns.Add(column)

    Dim newRow As DataRow
    Dim i As Integer
    For i = 0 To 9
        newRow = table.NewRow()
        newRow("NewColumn") = i
        table.Rows.Add(newRow)
    Next i

    Try
        ' Remove a row and invoke AcceptChanges.
        Dim removedRow As DataRow = table.Rows(9)
        removedRow.Delete()
        removedRow.AcceptChanges()
    
    Catch rowException As System.Data.RowNotInTableException
        Console.WriteLine("Row not in table")
    End Try
End Sub 

注解

RowNotInTableException对已使用或方法删除的行调用以下方法时,将引发 Delete DataRowCollection.RemoveThe RowNotInTableException is thrown when invoking the following methods on a row that has been deleted with either the Delete or the DataRowCollection.Remove method.
