如何从服务器下载.MSI文件并从下载路径安装？ [英] How to download .MSI file from server and install from download path?

问题描述

我尝试下载.msi文件，其下载但是（它的大小为0字节）。我无法理解为什么会发生这种情况？请建议我正确的代码紧急。并建议如何通过c＃代码安装下载的文件。



我尝试过：



private void btnUpdate_Click（object sender，EventArgs e）

{

string url = @http：//www.http：// careusa。 co / update_files / PC_Cleaner.msi;

//创建WebClient实例

WebClient客户端=新WebClient（）;

// Hookup DownloadFileCompleted事件

client.DownloadFileCompleted + = new AsyncCompletedEventHandler（client_DownloadFileCompleted）;



//开始下载并将文件复制到c： \ temp

client.DownloadFileAsync（new Uri（url），@C：\NewFolder \PC_Cleaner.msi）; //路径 - 我要下载的地方---



}



void client_DownloadFileCompleted（object sender，AsyncCompletedEventArgs e）

{

MessageBox.Show（文件下载d）;



string installerFilePath; //安装

installerFilePath = @C：\NewFolder \PC_Cleaner.msi;

System.Diagnostics.Process installerProcess;

installerProcess = System.Diagnostics.Process.Start（installerFilePath，/ q）;

while（installerProcess.HasExited == false）

{

//表示用户进度

Application.DoEvents（）;

System.Threading.Thread.Sleep（250）;

}

MessageBox.Show（完成安装）;

}

I try to downlaod .msi file, its downloaded but (it size is 0 byte).I cannot understand why its happen? please suggest me correct code its urgent. And also suggest how to install downloaded file through c# code.

What I have tried:

private void btnUpdate_Click(object sender, EventArgs e)

// Create an instance of WebClient
WebClient client = new WebClient();
// Hookup DownloadFileCompleted Event
client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted);

// Start the download and copy the file to c:\temp
client.DownloadFileAsync(new Uri(url), @"C:\NewFolder\PC_Cleaner.msi");//path-where i want to download---

}

void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
{
MessageBox.Show("File downloaded");

string installerFilePath; //For install
installerFilePath = @"C:\NewFolder\PC_Cleaner.msi";
System.Diagnostics.Process installerProcess;
installerProcess = System.Diagnostics.Process.Start(installerFilePath, "/q");
while (installerProcess.HasExited == false)
{
//indicate progress to user
Application.DoEvents();
System.Threading.Thread.Sleep(250);
}
MessageBox.Show("done installing");
}
