在.net 2.0应用程序中加载.net 3.5 wpf表单

关于此类主题的第一站应该是WPF Migration and Interoperability .特别是你会发现 Walkthrough: Hosting a Windows Presentation Foundation Control in Windows Forms 让你开始。

ElementHost 已引入。NET框架3.0。

如果你需要保护你的应用程序免受这些程序集缺失的影响,你必须引入一层间接层,并且只加载 ElementHost 在成功检测后的运行时。NET Framework 3.5,有关后者的提示,请参阅下文。

.NET Framework版本和service pack检测:

• How to detect what .NET Framework versions and service packs are installed
• MSDN: How to determine which versions of the .NET Framework are installed and whether service packs have been applied
• 代码项目( w/源代码 Using managed code to detect what .NET Framework versions and service packs are installed

要在Win32窗体中承载WPF控件,您需要使用ElementHost控件。将此控件拖放到窗口上,并将其Child属性设置为要显示的WPF窗体。

看看是否。无论是否安装了Net 3.5,您都可以尝试加载仅存在于3.5中的程序集

例如,以下是一种确定是否安装了Net 3.5 Sp1的方法:

        private static bool IsDotNet35Sp1Installed()
        {
            try
            {
                Assembly.ReflectionOnlyLoad(
                    "System.Data.Entity, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089");
            }
            catch (FileNotFoundException)
            {
                return false;
            }
            return true;
        }

我使用以下代码在.net 2.0 windows窗体主机中加载了一个包含3.5 wpf控件的dll。加载的控件包含ElementHost对象。

Dim dllPath As String = "C:\ProjectsTest\TestSolution\ActiveXUser\bin\Debug\TestControl.dll"
If Not File.Exists(dllPath) Then
Return
End If

Dim versionInformation As String
versionInformation = Environment.Version.Major.ToString + Environment.Version.Minor

Dim loadedAssembly As [Assembly] = [Assembly].LoadFile(dllPath)

Dim mytypes As Type() = loadedAssembly.GetTypes()

Dim t As Type = mytypes(1)
Dim obj As [Object] = Activator.CreateInstance(t)

versionInformation = Environment.Version.Major.ToString + Environment.Version.Minor
Me.Panel1.Controls.Add(obj)
