使用C＃程序运行一个可执行程序 [英] using C# Process to run a Executable program

问题描述

我是一个生物信息学的人，我用C＃我的工作。我一直使用C＃进程运行可执行程序几次。这一次，我有一个新的问题。我下载了Windows中的exe文件的程序命名爆炸（的 http://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Web&PAGE_TYPE=BlastDocs&DOC_TYPE=Download ）。如果我在键入命令是：

I am a Bioinformatic person and I use C# for my work. I have been using Processes in C# to run Executable programs several times. This time I have a new issue. I have downloaded an exe file in Windows for a program named Blast(http://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Web&PAGE_TYPE=BlastDocs&DOC_TYPE=Download). If I type in my command which is :

blastp -query input.txt -db pdbaa -out output.txt

它工作正常。但是，当我将复制一个记事本粘贴命令时，将给出一个错误。我搜索了这个问题，我发现，这是一个编码的问题UTF-8与ISO-拉丁文（的 http://biostar.stackexchange.com/questions/7997/an-error-by-using-ncbi-blast-2-2 -25-上的窗户被复制和粘贴引起）。

it works fine. But when I copy paste the command from a notepad it will give an error. I searched for the problem and I found that it is an "encoding problem UTF-8 versus ISO-latin" (http://biostar.stackexchange.com/questions/7997/an-error-by-using-ncbi-blast-2-2-25-on-windows) which is caused by copy and paste.

现在，我要运行C＃中的进程调用的exe文件，我得到了同样的问题，我想这是因为该过程不会像复制和粘贴。这里是我的代码：

Now that I want to run the process from c# to call the exe file I get the same problem and I guess it is because the process does something like copy and paste. Here is my code:

 public void Calculate()
    {
        Process proc = new Process();
        proc.StartInfo.WorkingDirectory = Program.NCBIBlastDirectory;
        proc.StartInfo.FileName = @"C:\Program Files\NCBI\blast-2.2.25+\bin\blastp.exe";
        proc.StartInfo.Arguments = "blastp -query input.txt -db pdbaa -out output.txt";
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.RedirectStandardError = true;
        proc.StartInfo.RedirectStandardError = true;
        proc.Start();
        proc.WaitForExit();
        proc.Close();
    }

你有什么想法，我怎么能解决这个问题？

Do you have any idea how I can solve this?

先谢谢了。

推荐答案

有一个问题，我可以看到的是在该行，你设置参数：

One problem I can see is in the line where you set the Arguments:

proc.StartInfo.Arguments = "blastp -query input.txt -db pdbaa -out output.txt";

我觉得你的意思是：

I think you meant:

proc.StartInfo.Arguments = "-query input.txt -db pdbaa -out output.txt";

所以，你不需要在参数再次指定可执行文件的名称 - 这就是filename是

So you don't need to specify the executable name again in the Arguments - that's what FileName is for.

另一件事是，有很多的不表现太清楚，如果你不使用shell-执行启动它们的应用程序。第一次尝试将其与壳执行（显然没有任何重定向性病*），如果它工作的方式，那么你就会知道什么问题是 - 尽管恐怕没有多少你可以做些什么

The other thing is that there are a lot of applications which don't behave too well if you don't use shell-execute to start them. Try it first with shell-execute (and obviously without redirecting any std*), and if it works that way, then you'll know what the issue is - although I'm afraid there's not much you can do about it.

另外，为什么是行

proc.StartInfo.RedirectStandardError = true;

重复两次？

repeated twice?
