Remove(DataTableMapping)
从集合中移除指定的 DataTableMapping 对象。Removes the specified DataTableMapping object from the collection.
public:
void Remove(System::Data::Common::DataTableMapping ^ value);
public void Remove (System.Data.Common.DataTableMapping value);
member this.Remove : System.Data.Common.DataTableMapping -> unit
Public Sub Remove (value As DataTableMapping)
参数
- value
- DataTableMapping
要移除的 DataTableMapping 对象。The DataTableMapping object to remove.
适用于
Remove(Object)
从集合中移除指定的 DataTableMapping 对象。Removes the specified DataTableMapping object from the collection.
public:
virtual void Remove(System::Object ^ value);
public void Remove (object? value);
public void Remove (object value);
abstract member Remove : obj -> unit
override this.Remove : obj -> unit
Public Sub Remove (value As Object)
参数
- value
- Object

实现
例外
指定的对象不是 DataTableMapping 对象。The object specified was not a DataTableMapping object.
指定的对象不在集合中。The object specified is not in the collection.
示例
下面的示例搜索 DataTableMapping 集合中的。The following example searches for a DataTableMapping within the collection. 如果集合中存在该映射,则将其删除。If the mapping exists in the collection, it is removed. 如果集合中不存在映射,则会将其添加到集合中,并显示其索引。If the mapping does not exist within the collection, it is added to the collection and its index is displayed. 该示例假设 DataTableMappingCollection 已创建一个集合和一个 DataTableMapping 对象。The example assumes that a DataTableMappingCollection collection and a DataTableMapping object have been created.
public void ChangedMyMind()
{
// ...
// create mappings and mapping
// ...
if (mappings.Contains((Object) mapping))
{
mappings.Remove((Object) mapping);
}
else
{
mappings.Add((Object) mapping);
Console.WriteLine("Index of new mapping: "
+ mappings.IndexOf((Object) mapping));
}
}
Public Sub ChangedMyMind()
' ...
' create mappings and mapping
' ...
If mappings.Contains(CType(mapping, Object)) Then
mappings.Remove(CType(mapping, Object))
Else
mappings.Add(CType(mapping, Object))
Console.WriteLine("Index of new mapping: " _
+ mappings.IndexOf(CType(mapping, Object)).ToString())
End If
End Sub
