获取或设置分配给该流的字节数。

public:
 virtual property int Capacity { int get(); void set(int value); };
public virtual int Capacity { get; set; }
member this.Capacity : int with get, set
Public Overridable Property Capacity As Integer

属性值

Int32

流的缓冲区的可使用部分的长度。

例外

ArgumentOutOfRangeException

容量设置为负或小于流的当前长度。

ObjectDisposedException

当前流已关闭。

NotSupportedException

对不能修改其容量的流调用 set。

示例

此代码示例是为 MemoryStream 类提供的一个更大示例的一部分。

// Write the stream properties to the console.
Console::WriteLine( "Capacity = {0}, Length = {1}, "
"Position = {2}\n", memStream->Capacity.ToString(), memStream->Length.ToString(), memStream->Position.ToString() );

// Write the stream properties to the console.
Console.WriteLine(
    "Capacity = {0}, Length = {1}, Position = {2}\n",
    memStream.Capacity.ToString(),
    memStream.Length.ToString(),
    memStream.Position.ToString());

' Write the stream properties to the console.
Console.WriteLine( _
    "Capacity = {0}, Length = {1}, Position = {2}", _
    memStream.Capacity.ToString(), _
    memStream.Length.ToString(), _
    memStream.Position.ToString())

注解

Capacity 是系统提供的字节数组的缓冲区长度。 Capacity 不能设置为小于流的当前长度的值。
