Question

我需要创建一个VB.NET应用程序，它接受 Windows窗体应用程序的源代码并编译它。我使用此link作为参考。

我要创建的Windows窗体应用程序

Public Class Form2
Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    MsgBox("test")
End Sub

结束班

我编译代码的VB.NET应用程序

Imports System.IO
Imports System.Reflection
Imports System.CodeDom
Imports System.CodeDom.Compiler
Imports Microsoft.VisualBasic

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim codeProvider As New VBCodeProvider()
    Dim icc As ICodeCompiler = codeProvider.CreateCompiler
    Dim Output As String = "Out.exe"
    Dim ButtonObject As Button = CType(sender, Button)

    textBox2.Text = ""
    Dim parameters As New CompilerParameters()
    Dim results As CompilerResults
    'Make sure we generate an EXE, not a DLL
    parameters.GenerateExecutable = True
    parameters.OutputAssembly = Output
    results = icc.CompileAssemblyFromSource(parameters, textBox1.Text)

    If results.Errors.Count > 0 Then
        'There were compiler errors
        textBox2.ForeColor = Color.Red
        Dim CompErr As CompilerError
        For Each CompErr In results.Errors
            textBox2.Text = textBox2.Text &
            "Line number " & CompErr.Line &
            ", Error Number: " & CompErr.ErrorNumber &
            ", '" & CompErr.ErrorText & ";" &
            Environment.NewLine & Environment.NewLine
        Next
    Else
        'Successful Compile
        textBox2.ForeColor = Color.Blue
        textBox2.Text = "Success!"
        'If we clicked run then launch the EXE
        If ButtonObject.Text = "Run" Then Process.Start(Output)
    End If
End Sub

Textbox1.text包含我提供的第一个代码。当我运行程序时，它给了我这个错误

Line number 0, Error Number: BC30420, ''Sub Main' was not found in 'Out'.;

Line number 2, Error Number: BC30002, 'Type 'EventArgs' is not defined.;

Line number 3, Error Number: BC30451, ''MsgBox' is not declared. It may be inaccessible due to its protection level.;

Line number 3, Error Number: BC32017, 'Comma, ')', or a valid expression continuation expected.;

嗯，你错过了很多东西。

在您传递给CompilerParameters的{{1}}中，您必须指定目标exe-type，默认为“/ target：exe”，这意味着Console可执行文件（然后编译器尝试查找）输入点的 Sub Main（），因此您必须为WindowsForms项目指定“/ target：winexe”。

您还必须在要编译的源代码中指定所需的CodeDomProvider ...否则将无法解析，并且对于源代码所需的.NET程序集引用相同，您必须指定所有这些都在你的Imports。

最后你应该指定主类的名称，然后你就可以编译它了。

我将展示一个可以适应/替换当前源代码的工作示例：
