为什么我收到错误 CS0246:找不到类型或命名空间名称?

问题描述

我正在使用 Snarl C# API向 snarl 发送通知.

I am using Snarl C# API to send notifications to snarl.

现在我已将上述 url 的内容保存在一个名为 SnarlNetwork.cs 的文件中，我的 test.cs 文件的内容是:

Now I have saved the content of above url in a file named SnarlNetwork.cs and the content of my test.cs file are:

using SnarlNetworkProtocol;
using System;
class test
{
    public static void Main(String[] args)
    {
        SNP snarl_object = new SNP();
        string hostname = "localhost";
        string hostport = "9887";
        string appName = "Spotify";

        bool val = snarl_object.register(hostname, hostport, appName);

        if (val == true)
        {
            string title = "hello";
            string message = "world";
            string timeout = "5";
            bool newval = snarl_object.notify(hostname, hostport, appName, null, title, message, timeout);

            if (newval == true)
            {
                Console.WriteLine("sucessfull");

            }
        }
    }

}

现在，当我尝试使用 csc test.cs 编译我的 test.cs 文件时，我收到以下错误:

Now when I try to compile my test.cs file using csc test.cs I get the following error:

C:UsersNoobcsharp>csc test.cs
Microsoft (R) Visual C# 2008 Compiler version 3.5.30729.4926
for Microsoft (R) .NET Framework version 3.5
Copyright (C) Microsoft Corporation. All rights reserved.

test.cs(1,7): error CS0246: The type or namespace name 'SnarlNetworkProtocol' could not be found (are you missing a using directive or an assembly reference?)

那么，我在这里做错了什么，因为根据我的说法，我没有错过任何 using 指令.

So, what am I doing wrong here because according to me I am not missing any using directive.

推荐答案

这是问题所在:

C:UsersNoobcsharp>csc test.cs

您尚未添加对 DLL 的引用.你需要这样的东西:

You haven't added a reference to the DLL. You need something like:

C:UsersNoobcsharp>csc test.cs /r:SnarlNetwork.dll

(或任何调用程序集).

(or whatever the assembly is called).

或者，如果您没有将其作为单独的库，只需编译这两个文件:

Alternatively, if you haven't got it as a separate library, just compile both files:

C:UsersNoobcsharp>csc test.cs SnarlNetwork.cs

如果您尚未编译程序集但想要，则可以使用:

If you haven't compiled an assembly but want to, you can use:

csc /target:library /out:SnarlNetwork.dll SnarlNetwork.cs

csc Test.cs /r:SnarlNetwork.dll

(实际上，在这种特殊情况下，指定输出文件是不必要的，但它仍然更清晰......)

(In fact, specifying the output file is unnecessary in this particular case, but it's still clearer...)
