我无法在C＃代码中正确调用msiexec.exe。 [英] I cannot call msiexec.exe correctly in C# code.

问题描述

Process process = new Process();
process.StartInfo.FileName = @"msiexec.exe"; 

process.StartInfo.Arguments = string.Format(@"/i E:\My Steup Files\Installer.msi");

process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.CreateNoWindow = false;
process.Start();
process.WaitForExit();

执行上面的代码时，会出现Windows Installer帮助窗口。

我认为参数是正确的，我不知道为什么它不能执行。

有谁知道原因？谢谢你的帮助！

when execute above code, the Windows Installer help window comes out.
I think the parameter is correct, I don't know why it cannot execute.
Does anyone know the reason? Thanks for your help!

推荐答案

嗨seshaliang，



你可以尝试一下

Process.Start（msiexec.exe）;

Hi seshaliang,

you can try it
Process.Start("msiexec.exe");

对不起。我没有找到错误点，所以我的问题不是很清楚。

真正的原因是msi文件包含空格的路径，然后窗口安装程序帮助dailog弹出。

我认为它用空格分析参数。

示例：msiexec.exe / i E：\ 我的Steup文件 \ Installer.msi / qn

为路径添加引号是好。现在cmdLine是：msiexec.exe / iE：\ 我的Steup文件 \Installer.msi/ qn

I am sorry. I didn't find the error point so my question isn't very clear.
The real cause is the path of msi file contains space, then window installer help dailog pops up.
I think it analysises params by spaces.
example: msiexec.exe /i E:\My Steup Files\Installer.msi /qn
Add quotes for the path is OK. Now the cmdLine is: msiexec.exe /i "E:\My Steup Files\Installer.msi" /qn

//请尝试此代码：

流程流程=新流程（）;

流程.StartInfo.WorkingDirectory = @E：\ Source; //设置exe文件所在的工作目录。

process.StartInfo.FileName =msiexec.exe;



process.StartInfo.Arguments = string.Format（@/ i E：\ My Steup Files \Installer.msi）; //传递参数的数量。



process.StartInfo.UseShellExecute = false;

process.StartInfo.CreateNoWindow = false;

process.Start（）;

process.WaitForExit（）;

//Please try this code:
Process process = new Process();
process .StartInfo.WorkingDirectory = @"E:\Source"; //sets the working directory in which the exe file resides.
process.StartInfo.FileName = "msiexec.exe";

process.StartInfo.Arguments = string.Format(@"/i E:\My Steup Files\Installer.msi"); //Pass the number of arguments.

process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = false;
process.Start();
process.WaitForExit();
