装载组件无法正常工作
我尝试在C＃中将程序集加载到我的源代码中。 所以我首先编译源文件：
private bool testAssemblies(String sourceName) { FileInfo sourceFile = new FileInfo(sourceName); CodeDomProvider provider = null; bool compileOk = false; // Select the code provider based on the input file extension. if (sourceFile.Extension.ToUpper(CultureInfo.InvariantCulture) == ".CS") { provider = CodeDomProvider.CreateProvider("CSharp"); } else if (sourceFile.Extension.ToUpper(CultureInfo.InvariantCulture) == ".VB") { provider = CodeDomProvider.CreateProvider("VisualBasic"); } else { Console.WriteLine("Source file must have a .cs or .vb extension"); } if (provider != null) { // Format the executable file name. // Build the output assembly path using the current directory // and _cs.exe or _vb.exe. String exeName = String.Format(@"{0}\{1}.exe", System.Environment.CurrentDirectory, sourceFile.Name.Replace(".", "_")); CompilerParameters cp = new CompilerParameters(); // Generate an executable instead of // a class library. cp.GenerateExecutable = true; // Specify the assembly file name to generate. cp.OutputAssembly = exeName; // Save the assembly as a physical file. cp.GenerateInMemory = false; // Set whether to treat all warnings as errors. cp.TreatWarningsAsErrors = false; // Invoke compilation of the source file. CompilerResults cr = provider.CompileAssemblyFromFile(cp, sourceName); if (cr.Errors.Count > 0) { // Display compilation errors. Console.WriteLine("Errors building {0} into {1}", sourceName, cr.PathToAssembly); foreach (CompilerError ce in cr.Errors) { Console.WriteLine(" {0}", ce.ToString()); Console.WriteLine(); } } else { // Display a successful compilation message. Console.WriteLine("Source {0} built into {1} successfully.", sourceName, cr.PathToAssembly); } // Return the results of the compilation. if (cr.Errors.Count > 0) { compileOk = false; } else { compileOk = true; } } return compileOk; } 这很好用，但如果我以后尝试加载程序集，我总是会遇到exception：

我的加载方法如下所示：
if (testAssemblies("C:\\Users\\Roflcoptr\\Desktop\\hello.cs")) { Assembly a = Assembly.Load("C:\\Users\\Roflcoptr\\Documents\\Visual Studio 2008\\Projects\\Prototype_Ver1\\Prototype_Ver1\\bin\\Debug\\hello_cs.exe"); }
任何想法为什么它不起作用？
我认为你的语法错了。 Assembly.load（string）需要程序集名称
Assembly.Load("SampleAssembly, Version=1.0.2004.0, Culture=neutral, PublicKeyToken=8744b20f8da049e3");
还要确保你正在使用正确的超载来满足你的需求（通常确实是Assembly.Load） http://blogs.msdn.com/b/suzcook/archive/2003/05/29/57143.aspx
编辑使用此：
AssemblyName an = AssemblyName.GetAssemblyName(filePath); Assembly.Load(an);
