NameObjectCollectionBase.ICollection.CopyTo(Array, Int32) 方法

定义

命名空间:
System.Collections.Specialized
程序集:
System.Collections.Specialized.dll, System.dll, netstandard.dll

从目标数组的指定索引处开始将整个 NameObjectCollectionBase 复制到兼容的一维 Array。Copies the entire NameObjectCollectionBase to a compatible one-dimensional Array, starting at the specified index of the target array.

 virtual void System.Collections.ICollection.CopyTo(Array ^ array, int index) = System::Collections::ICollection::CopyTo;
void ICollection.CopyTo (Array array, int index);

参数

array
Array

一维 Array，它是从 NameObjectCollectionBase 复制的元素的目标。The one-dimensional Array that is the destination of the elements copied from NameObjectCollectionBase. Array 必须具有从零开始的索引。The Array must have zero-based indexing.

index
Int32

array 中要从其开始复制的从零开始的索引。The zero-based index in array at which copying begins.

实现

CopyTo(Array, Int32)

异常

ArgumentNullException

array 为 null。array is null.

ArgumentOutOfRangeException

index 小于零。index is less than zero.

ArgumentException

array 是多维的。array is multidimensional.

- 或 --or- 源 NameObjectCollectionBase 中的元素个数大于从 index 到目标 array 末尾之间的可用空间。The number of elements in the source NameObjectCollectionBase is greater than the available space from index to the end of the destination array.

InvalidCastException

无法自动将源 NameObjectCollectionBase 的类型转换为目标 array 的类型。The type of the source NameObjectCollectionBase cannot be cast automatically to the type of the destination array.

注解

指定的数组必须是兼容的类型。The specified array must be of a compatible type.

此方法使用 Array.Copy 复制元素。This method uses Array.Copy to copy the elements.

虽然 ICollection.CopyTo 方法默认情况下对 COM 客户端不可见，但继承 NameObjectCollectionBase 类可以将其公开，并可能导致在 COM 客户端中产生不需要的行为。While the ICollection.CopyTo method is not visible to COM clients by default, inheriting the NameObjectCollectionBase class can expose it and can cause undesirable behavior in COM clients.

此方法是一个 O （n）操作，其中 n 是 Count的。This method is an O(n) operation, where n is Count.
