视觉工作室。 无法启动程序 '' 系统找不到指定的文件

Question

Its my first program on Visual Studio on C#. I did not write my own code and Im trying to open any template projects with simple console writes.

// ConsoleApplication1.cpp : This file contains the 'main' function. Program execution begins and ends there.
//

#include <iostream>

int main()
{
    std::cout << "Hello World!\n";
}

// Run program: Ctrl + F5 or Debug > Start Without Debugging menu
// Debug program: F5 or Debug > Start Debugging menu

// Tips for Getting Started: 
//   1. Use the Solution Explorer window to add/manage files
//   2. Use the Team Explorer window to connect to source control
//   3. Use the Output window to see build output and other messages
//   4. Use the Error List window to view errors
//   5. Go to Project > Add New Item to create new code files, or Project > Add Existing Item to add existing code files to the project
//   6. In the future, to open this project again, go to File > Open > Project and select the .sln file

However Im receiving error that I do not know how to solve.

Errors: Unable to build properly. When I try to build, there are tons of errors eg cannot open source file ... (tons of this) the global scope has no .... (tons of this)
And when I try to run, obviously it wont run. It will tell me "Unable to start program. 'C:\\repo....\\Debug\\ConsoleApplication1.exe' The system cannot find the file specified."

This is my very first program and Im unable to run it. I believe its probably due to file path of the project - unable to find the appropriate files. I have no idea which setting to tweak as well... Probably a very simple solution but I cant find it online. Thanks.

Answer 1

According to your example code, this is a C ++ project and not a C # project. If you want to create a C# project ,you need different code.

If you created a c++ project, and got this error. I sugges you could follow the following steps to resolve the issue:

1,You should build the project before running it.

The cause of this error is most likely because you haven't built your project from Build > Build Solution . The reason you're getting this error when you try to run your project is because Visual Studio can't find the executable file that should be produced when you build your project.

2,Check if the linker output file matches the path, name and extension of the target file.

Right Click Project Name > Properties -> Linker > General -> Output File > $(OutDir)$(TargetName)$(TargetExt)
