需要使用VBCodeProvider编译Silverlight 3.0的DLL的帮助吗

我很难动态编译用于Silverlight 3.0的DLL。我的目标是采用用户提供的一些规则,并将它们编译成DLL以进行自定义编辑。

我在VisualStudio中创建了一个Silverlight类库项目,以获取用于编译Silverlight类库的命令行。基于这一点以及使用VBCodeProvider编译VB的许多示例,我提出了以下将字符串中的代码编译为DLL的方法:

Public Function Compile(ByVal code As String, ByVal assemblyName As String) As CompilerResults
    ' set the compiler parameters
    Dim parameters As CompilerParameters = New CompilerParameters()
    parameters.OutputAssembly = assemblyName
    parameters.GenerateInMemory = False
    parameters.GenerateExecutable = False
    parameters.IncludeDebugInformation = True

    ' constants for the silverlight assembly directories
    Dim sdkDir As String = "c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\Silverlight\v3.0\"
    Dim clientDir As String = "c:\Program Files (x86)\Microsoft SDKs\Silverlight\v3.0\Libraries\Client\"
    Dim riaDir As String = "C:\Program Files (x86)\Microsoft SDKs\RIA Services\v1.0\Libraries\Silverlight\"

    ' set referenced assemblies
    parameters.ReferencedAssemblies.Clear()
    parameters.ReferencedAssemblies.Add(sdkDir + "mscorlib.dll")
    parameters.ReferencedAssemblies.Add(sdkDir + "System.Core.dll")
    parameters.ReferencedAssemblies.Add(sdkDir + "system.dll")
    parameters.ReferencedAssemblies.Add(sdkDir + "System.Net.dll")
    parameters.ReferencedAssemblies.Add(sdkDir + "System.Windows.Browser.dll")
    parameters.ReferencedAssemblies.Add(sdkDir + "System.Windows.dll")
    parameters.ReferencedAssemblies.Add(sdkDir + "System.Xml.dll")

    ' build compiler options for sdk path to point to Silverlight.
    Dim options As String

    options = "/sdkpath:""" + sdkDir + "\"" "
    options = options + "/define:""SILVERLIGHT=1"""

    parameters.CompilerOptions = options

    ' compile
    Dim provider = New VBCodeProvider()
    Return provider.CompileAssemblyFromSource(parameters, code)
End Function

我的单元测试类的代码如下:

Public Sub CompileTest()

    ' Assemble
    Dim builder As StringBuilder = New StringBuilder()
    builder.AppendLine("Imports System")
    builder.AppendLine("Namespace Namespace1")
    builder.AppendLine("Public Class Class1")
    builder.AppendLine("Public Sub Test()")
    builder.AppendLine("Console.WriteLine(""Hello Compilation"")")
    builder.AppendLine("Console.ReadLine()")
    builder.AppendLine("End Sub")
    builder.AppendLine("End Class")
    builder.AppendLine("End Namespace")

    Dim assemblyName As String = ".\TestAssembly.dll"

    ' Act
    Dim compiler As SilverlightCompiler = New SilverlightCompiler()
    Dim cr As CompilerResults = compiler.Compile(builder.ToString(), assemblyName)

    ' Assert
    Assert.AreEqual(0, cr.Errors.Count)
End Sub

vbc:命令行(0,0):错误BC2010:编译失败:“在类“Microsoft.VisualBasic.Information”中找不到成员“IsNumeric”。这种情况通常是由不匹配的“Microsoft.VisualBasic.dll”造成的

为什么? 我首先尝试调用该方法。

有人能解释如何成功地将源代码动态编译到Silverlight兼容的类库中吗?蒂亚。
