如何：保存和恢复布局

下面的示例演示了如何把图表保存到内存流，然后恢复。

C#	复制代码
using System.IO; // ... Stream stream = new MemoryStream(); // ... // Save the chart. stream.Seek(0, System.IO.SeekOrigin.Begin); chartControl1.SaveToStream(stream); // Load the chart. stream.Seek(0, System.IO.SeekOrigin.Begin); chartControl1.LoadFromStream(stream);

复制代码

using System.IO;
// ...

Stream stream = new MemoryStream();
// ...

// Save the chart.
stream.Seek(0, System.IO.SeekOrigin.Begin);
chartControl1.SaveToStream(stream);

// Load the chart.
stream.Seek(0, System.IO.SeekOrigin.Begin);
chartControl1.LoadFromStream(stream);

Visual Basic	复制代码
Imports System.IO ' ... Dim stream As System.IO.Stream stream = New System.IO.MemoryStream() ' ... ' Save the chart. stream.Seek(0, System.IO.SeekOrigin.Begin) ChartControl1.SaveToStream(stream) ' Load the chart. stream.Seek(0, System.IO.SeekOrigin.Begin) ChartControl1.LoadFromStream(stream)

Visual Basic

复制代码

Imports System.IO
' ...

Dim stream As System.IO.Stream
stream = New System.IO.MemoryStream()
' ...

' Save the chart.
stream.Seek(0, System.IO.SeekOrigin.Begin)
ChartControl1.SaveToStream(stream)

' Load the chart.
stream.Seek(0, System.IO.SeekOrigin.Begin)
ChartControl1.LoadFromStream(stream)
