我一直试图和我的同事一起解决这个问题
我使用Ngen制作原生图像并提高我在客户端的应用程序性能。
假设Exe文件名是Example.exe
我在应用程序中尝试做的是我做ngen安装example.exe,并且ngen将为assebmlies安装本机图像
不过这是问题:
如果我尝试使用Elevated CMD并运行C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen Display example.exe
显示example.exe文件名和本机映像的版本,但是,使用以下代码在Windows窗体c#中执行相同操作,它不显示example.exe文件的文件名和版本,并显示相反,例如Telerik等
所以我的问题是为什么CMD在进程返回依赖关系而不是文件名和版本本身时返回正确的结果?
这是我的一些代码:
public static bool Run()
{
var f = new Loading();
bool state = false;
var b = new BackgroundWorker();
string runtimeStr = RuntimeEnvironment.GetRuntimeDirectory();
string ngenStr = Path.Combine(runtimeStr, "ngen");
Process process = new Process
{
StartInfo =
{
FileName = ngenStr,
WindowStyle = ProcessWindowStyle.Hidden,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
CreateNoWindow = false
}
};
if (Environment.OSVersion.Version.Major >= 6)
{
process.StartInfo.Verb = "runas";
}
process.StartInfo.Arguments = "display " + Application.ProductName;
process.Start();
// process.WaitForExit();
string stdoutx = process.StandardOutput.ReadToEnd();
process.WaitForExit();
}
但是stdoutx字符串不包含example.exe文件名或版本
编辑:应该是什么和什么的例子:
这就是cmd返回的正确结果:

答案 0 :(得分:2)
是的,你没有正确地这样做。您正在使用的命令的语法是:
ngen.exe display [assemblyName | assemblyPath]
请注意 assemblyName 和 assemblyPath 之间的区别。当您从cmd.exe运行它时,键入&#34;示例&#34;。并因此指定(部分)程序集名称。在您的代码中,您使用了&#34; example.exe&#34;。并且Environment.CurrentDirectory是偶然设置的,这是一个常见的事故。所以Ngen.exe可以找到文件并且它很健谈。不仅列出程序集名称,还列出其所有依赖项的本机映像。像Klik.Windows.Forms.EntryLib等。
不是唯一的问题,请注意您指定了部分程序集名称。您希望确保程序集的特定版本是否已被添加。使代码看起来像这样:
process.StartInfo.Arguments = "display \"" +
System.Reflection.Assembly.GetEntryAssembly().FullName + "\"";
使用Project&gt;进行测试属性&gt;调试选项卡&gt;取消&#34;启用Visual Studio托管过程&#34;复选框。
要担心的次要问题是本机映像(x86 vs x64)的位数以及提升您的应用程序以便安装本机映像,这些内容通常只有在您的应用程序安装时才有效。
