Vb.net 执行运行时代码参数

Vb.net 执行运行时代码参数,vb.net,Vb.net,以下是一些在运行时执行代码的代码: Dim SourceCode As String = txtCode.Text Dim Dlls() As String = {"System.dll", "System.Core.dll", "System.Data.dll", "System.Windows.Forms.dll"} 'Any referenced dll's Dim Compiler As New VbCompiler(SourceCode, Dlls)

以下是一些在运行时执行代码的代码:

    Dim SourceCode As String = txtCode.Text

    Dim Dlls() As String = {"System.dll", "System.Core.dll", "System.Data.dll", "System.Windows.Forms.dll"} 'Any referenced dll's
    Dim Compiler As New VbCompiler(SourceCode, Dlls)
    Dim CodeAssembly As Assembly = Compiler.Compile
    If Compiler.Successful Then
        Dim instance As Object = CodeAssembly.CreateInstance("TestCode.Class1")
        Dim CodeType As Type = instance.GetType
        Dim Info As MethodInfo = CodeType.GetMethod("ShowMessage")
        Info.Invoke(instance, Nothing)
    Else
        For Each i As CompilerError In Compiler.Errors
            MsgBox(i.ErrorText)
        Next
    End If
txtCode.text=:

Imports System.Windows.Forms
Namespace TestCode
    Class Class1
        Sub ShowMessage()
            MessageBox.Show("Test")
        End Sub
    End Class
End Namespace
这很好用。我想知道如何将参数传递给函数。即

txtCode.text=:

Imports System.Windows.Forms
Namespace TestCode
    Class Class1
        Sub ShowMessage(ByVal x As String)
            MessageBox.Show(x)
        End Sub
    End Class
End Namespace 
我想使用字符串作为参数运行'ShowMessage函数,例如Test

我很确定这是在以下几行:

    Dim Info As MethodInfo = CodeType.GetMethod("ShowMessage")
    Info.Invoke(instance, Nothing)

但我无法让它工作。

您需要传递字符串值

 Info.Invoke(instance, New Object(){"Test"})
编辑:两个参数

 Info.Invoke(instance, New Object(){"First","Second"})

子ShowMessageByVal x作为字符串MessageBox.Showx结束Sub@SimonCanning-对不起!你想说点什么吗?看看Invoke方法的第二个参数。这样就可以将参数传递给ShowMessage。
