注解

枚举 C# 或 Microsoft Visual Basic 中的集合

ResourceQualifierVectorView 是可枚举的，因此可以使用特定于语言的语法（如 C# 中的 foreach ）枚举集合中的项。编译器为你执行类型强制转换，你无需显式转换为 IEnumerable<ResourceQualifier> 。如果需要显式强制转换（例如，如果要调用 GetEnumerator），请使用 ResourceQualifier 约束强制转换为 IEnumerable<T>。

属性

Size	获取视图中的 ResourceQualifier 对象数。

方法

First()	返回一个迭代器，用于枚举视图中的项。
GetAt(UInt32)	返回视图中指定索引处的 ResourceQualifier 。
GetMany(UInt32, ResourceQualifier[])	返回从视图中的指定索引处开始的 ResourceQualifier 对象。
IndexOf(ResourceQualifier, UInt32)	返回视图中指定 ResourceQualifier 的索引。
