通过Visual Studio中的C＃类编译C ++代码

Question

I use this method to compile C++ file in VS. But even i provide the correct file it returns false. Can any one help me... This is class called CL

class CL
{
    private const string clexe = @"cl.exe";
    private const string exe = "Test.exe", file = "test.cpp";
    private string args;

    public CL(String[] args)
    {
        this.args = String.Join(" ", args);
        this.args += (args.Length > 0 ? " " : "") + "/Fe" + exe + " " + file;
    }

    public Boolean Compile(String content, ref string errors)
    {
        if (File.Exists(exe))
            File.Delete(exe);
        if (File.Exists(file))
            File.Delete(file);

        File.WriteAllText(file, content);

        Process proc = new Process();
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.RedirectStandardOutput = true;
        proc.StartInfo.RedirectStandardError = true;
        proc.StartInfo.FileName = clexe;
        proc.StartInfo.Arguments = this.args;
        proc.StartInfo.CreateNoWindow = true;

        proc.Start();
        //errors += proc.StandardError.ReadToEnd();
        errors += proc.StandardOutput.ReadToEnd();

        proc.WaitForExit();

        bool success = File.Exists(exe);

        return success;
    }
}

This is my button click event

    private void button1_Click(object sender, EventArgs e)
    {
        string content = "#include <stdio.h>\nmain(){\nprintf(\"Hello world\");\n}\n";
        string errors = "";

        CL k = new CL(new string[] { });
        if (k.Compile(content, ref errors))
            Console.WriteLine("Success!");
        else
            MessageBox.Show("Errors are : ", errors);
    } 

Answer 1

In your Visual Studio installation folder there should be the following path:

VC\bin\x86_amd64\1033\1033

There should be a clui.dll in this path. Copy it to the parent folder ( VC\\bin\\x86_amd64\\1033 ). This should solve your problem.

Maybe it is not relevant, but I think you miss a space in your command line...

this.args += (args.Length > 0 ? " " : "") + "/Fe" + exe + " " + file;

right after the "/Fe"
