定义

确定 IList 中特定项的索引。Determines the index of a specific item in the IList.

 virtual int System.Collections.IList.IndexOf(System::Object ^ value) = System::Collections::IList::IndexOf;
int IList.IndexOf (object value);
abstract member System.Collections.IList.IndexOf : obj -> int
override this.System.Collections.IList.IndexOf : obj -> int
Function IndexOf (value As Object) As Integer Implements IList.IndexOf

参数

value
Object

要在当前列表中定位的对象。The object to locate in the current list.

返回

Int32

如果在列表中找到该对象,则为值的索引,否则为 -1。The index of value if found in the list; otherwise, -1.

注解

此成员是显式接口成员的实现。This member is an explicit interface member implementation. 它只能在 Array 实例被强制转换为 IList 接口时使用。It can be used only when the Array instance is cast to an IList interface.
