从Vim中的用户定义命令切换到** insert **模式(Switch to **insert** mode from a user-defined command in Vim)

 我的一个朋友在做类似的事情，并帮助我解决了这个问题。 
 
 在第2步和第3步，我试图编写输入并使用进程标准输入和输出读取输出，而且，我试图使用.lnk来运行命令提示符。 所有这些都导致了错误。 
 
 解决方案是： 
 
 
 
 创建两个批处理文件，一个用于启动命令提示符，另一个用于编译.c文件（这些文件是在程序代码之外创建的）。 
 
 
 （运行时）使用编写的代码创建.c文件。 如果文件存在，请将其删除并创建一个新文件。 
 
 
 使用cmd.exe启动该过程。 
 
 
 运行批处理文件，使用Stream Writer将它们写入cmd.exe。 
 
 
 使用Stream Reader检索输出。 
 
 
 幸运的是，这有效！ 代码结束如下： 
 
string CompileC (string code)
{
    string path = @"C:\sample.c";
    string results = "";

    try
    {
        if (File.Exists(path))
            File.Delete(path);

        using (FileStream fs = File.Create(path))
        {
            byte[] codeText = new UTF8Encoding(true).GetBytes(code);
            fs.Write(codeText, 0, codeText.Length);
        }

        Process process = new Process();
        process.StartInfo.FileName = @"C:\Windows\system32\cmd.exe";
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardInput = true;
        process.StartInfo.RedirectStandardOutput = true;
        process.Start();

        using (StreamWriter sw = process.StandardInput)
        {
            if (sw.BaseStream.CanWrite)
            {
                //This batch starts up the Visual Studio Command Prompt.
                sw.WriteLine(@"C:\Startup.bat");
                //This batch does the compilation, once the Command Prompt
                //is running, using the 'cl' command.
                sw.WriteLine(@"C:\Compile.bat");
            }
        }

        using (StreamReader sr = process.StandardOutput)
        {
            if (sr.BaseStream.CanRead)
                results = sr.ReadToEnd();
        }
    }
    catch (Exception ex) { MessageBox.Show(ex.ToString()); }

    return results;
}

A friend of mine worked on something similar, and helped me to solve this problem.
 
On steps 2 and 3, I was trying to write the input and read the output using simply the process standard input and output, and also, I was trying to use an .lnk to run the Command Prompt. All those things caused the error.
 
The solution was:
 
 
 
Create two batch files, one to start up the Command Prompt and the other to compile the .c file (those were created outside the program's code).
 
 
(On runtime) Create the .c file, using the code written. If file exists, delete it and create a new one.
 
 
Start the process with cmd.exe.
 
 
Run the batch files, using a Stream Writer to write them in the cmd.exe.
 
 
Retrieve the output using a Stream Reader.
 
 
Fortunately, this worked! Code ended like this:
 
string CompileC (string code)
{
    string path = @"C:\sample.c";
    string results = "";

    try
    {
        if (File.Exists(path))
            File.Delete(path);

        using (FileStream fs = File.Create(path))
        {
            byte[] codeText = new UTF8Encoding(true).GetBytes(code);
            fs.Write(codeText, 0, codeText.Length);
        }

        Process process = new Process();
        process.StartInfo.FileName = @"C:\Windows\system32\cmd.exe";
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardInput = true;
        process.StartInfo.RedirectStandardOutput = true;
        process.Start();

        using (StreamWriter sw = process.StandardInput)
        {
            if (sw.BaseStream.CanWrite)
            {
                //This batch starts up the Visual Studio Command Prompt.
                sw.WriteLine(@"C:\Startup.bat");
                //This batch does the compilation, once the Command Prompt
                //is running, using the 'cl' command.
                sw.WriteLine(@"C:\Compile.bat");
            }
        }

        using (StreamReader sr = process.StandardOutput)
        {
            if (sr.BaseStream.CanRead)
                results = sr.ReadToEnd();
        }
    }
    catch (Exception ex) { MessageBox.Show(ex.ToString()); }

    return results;
}
