LogEntryInfos.Remove(Object) 方法

定义

LogEntryInfo 集合中删除 LogEntryInfos 对象。

public:
 void Remove(System::Object ^ index);
public void Remove (object index);
member this.Remove : obj -> unit
Public Sub Remove (index As Object)

参数

index
Object

要在集合中找到的 LogEntryInfo 对象的名称、ID 或索引。

示例

下面的代码示例使用名称作为索引从集合中删除项。
