WorkflowView.LoadViewState(Stream) 方法

定义

从二进制流还原视图状态信息。Restores view-state information from a binary stream.

public:
 void LoadViewState(System::IO::Stream ^ viewState);
public void LoadViewState (System.IO.Stream viewState);
member this.LoadViewState : System.IO.Stream -> unit
Public Sub LoadViewState (viewState As Stream)

参数

viewState
Stream

一个 BinaryReader,用于还原视图状态。A BinaryReader used to restore the view state.

示例

下面的示例演示如何 WorkflowView 通过 FileStream 使用标志创建对象 FileMode.Open 并将其传递给方法来加载对象的视图状态 LoadViewStateThe following example demonstrates how to load the view state for a WorkflowView object by creating a FileStream object with the FileMode.Open flag and passing it to the LoadViewState method. 视图状态文件是使用 SaveViewState 方法创建的。The view state file was created using the SaveViewState method.

public void LoadViewState()
{
    using (FileStream fs = new FileStream(@"viewstate.bin", FileMode.Open))
    {
        this.workflowView.LoadViewState(fs);
    }
}
Public Sub LoadViewState()
    Using fs As New FileStream("viewstate.bin", FileMode.Open)
        Me.workflowView.LoadViewState(fs)
    End Using
End Sub

注解

LoadViewState 还原以前通过调用 SaveViewState 方法保存的视图状态信息。LoadViewState restores view-state information previously saved by calling the SaveViewState method.

当需要自定义某个自定义设计器还原其视图状态的方式时可重写此方法。Override this method when you need to customize how a custom designer restores its view-state.
