Question

我正在使用CodeDom来允许自定义脚本（C＃）在我正在创建的应用程序中运行。在编写脚本时，我希望能够检查编译错误。代码在很晚的时候被添加到内存并编译到内存中，因此我不希望在编写脚本时编译的程序集保留在内存中。

实现这一目标的最佳方式是什么？

编译后是否可以从内存中删除程序集？

private void Item_Click(object sender, EventArgs e)
{
    List<string> assemblyNames = new List<string> { };
    List<string> code = new List<string> { };
    foreach (string str in GetCompileParameters())
            if (!assemblyNames.Contains(str))
                assemblyNames.Add(str);
    code.AddRange(GetScriptCode());

    CodeDomProvider provider = new Microsoft.CSharp.CSharpCodeProvider();
    CompilerParameters mCompileParams = new CompilerParameters(assemblyNames.ToArray());
    mCompileParams.GenerateInMemory = true;
    mCompileParams.CompilerOptions = "/target:library /optimize";

    CompilerResults results = provider.CompileAssemblyFromSource(mCompileParams, code.ToArray());
    if (results.Errors.HasErrors)
    {
        string error = "The following compile error occured:\r\n";
        foreach (CompilerError err in results.Errors)
            error += "File: " + err.FileName + "; Line (" + err.Line + ") - " + err.ErrorText + "\n";
        MessageBox.Show(error);
        return;
    }
    MessageBox.Show("No errors found");

    //Need to Remove assembly here
}

更新

谢谢基思。

对于任何感兴趣的人，这是我与Roslyn一起使用的新代码

using Roslyn.Compilers;
using Roslyn.Compilers.CSharp;

private void Item_Click(object sender, EventArgs e)
    {
        List<string> assemblyNames = new List<string> { }; 
        foreach (string str in GetCompileParameters())
                if (!assemblyNames.Contains(str))
                    assemblyNames.Add(str);

        SyntaxTree tree = SyntaxTree.ParseCompilationUnit(mScenario.GetScriptCode("ScriptName"));
        Compilation com = Compilation.Create("Script");
        com = com.AddReferences(new AssemblyFileReference(typeof(Object).Assembly.Location)); // Add reference mscorlib.dll
        com = com.AddReferences(new AssemblyFileReference(typeof(System.Linq.Enumerable).Assembly.Location)); // Add reference System.Core.dll
        com = com.AddReferences(new AssemblyFileReference(typeof(System.Net.Cookie).Assembly.Location)); // Add reference System.dll
        foreach (string str in assemblyNames)
            com = com.AddReferences(new AssemblyFileReference(str)); // Add additional references
        com = com.AddSyntaxTrees(tree);

        Diagnostic[] dg = com.GetDiagnostics().ToArray();
        if (dg.Length > 0)
        {
            string error = "The following compile error occured:\r\n";
            foreach (Diagnostic d in dg)
                error += "Info: " + d.Info + "\n";
            MessageBox.Show(error, "Compile Failed", MessageBoxButtons.OK, MessageBoxIcon.Error);
        } else {
            MessageBox.Show("No errors found.", "Code Compiler", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }
    }
