An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module

今天编写一个c++ clr程序调用c# dll，由于不熟，爆出一个错误

c# 类库代码：

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace CSharpDll0217{public class Class1{private string name;public string Name{get{return name;}set{name = "Your Name: " + value;}}}}

c++ clr 控制台程序代码：

// Clr0217.cpp : main project file.#include "stdafx.h"#using "D:\\hbj\\test\\test1024\\Debug\\CSharpDll0217.dll"using namespace CSharpDll0217;using namespace System;int main(array<System::String ^> ^args){    Console::WriteLine(L"Hello World");Class1 ^c1 = gcnew Class1;c1->Name = "zzj";Console::WriteLine(c1->Name);    return 0;}

然后就报错了：An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module

搜索了一下，stackoverflow上说工作路径保持一致，于是修改c# dll项目输出路径：Properties->Build->Outpath,使其与c++生产的exe同一目录

然后c++代码路径也顺便修改：

#using "D:\\hbj\\test\\test1024\\Debug\\CSharpDll0217.dll"

至此问题解决。
