我想知道如何检查特定位置的程序是否正在运行。例如,c:\loc1\test.exe和c:\loc2\test.exe是test.exe的两个不同位置。我只想知道c:\loc1\test.exe是否在运行,而不是所有test.exe实例。

bool isRunning = Process.GetProcessesByName("test")
.FirstOrDefault(p => p.MainModule.FileName.StartsWith(@"c:\loc1")) != default(Process);
这是我的改进后的函数:
private bool ProgramIsRunning(string FullPath)
{
string FilePath = Path.GetDirectoryName(FullPath);
string FileName = Path.GetFileNameWithoutExtension(FullPath).ToLower();
bool isRunning = false;
Process[] pList = Process.GetProcessesByName(FileName);
foreach (Process p in pList) {
if (p.MainModule.FileName.StartsWith(FilePath, StringComparison.InvariantCultureIgnoreCase))
{
isRunning = true;
break;
}
}
return isRunning;
}
并将其用作:
ProgramIsRunning(@"c:\loc1\test.exe");

32位进程无法访问64位进程的模块
的问题,最终使用了https://dev59.com/xG035IYBdhLWcg3wT-NC#5497319中提供的解决方案。 - Adrian C.using System.Diagnostics;
public bool IsProcessOpen(string name)
{
foreach (Process clsProcess in Process.GetProcesses()) {
if (clsProcess.ProcessName.Contains(name))
{
return true;
}
}
return false;
}
类似于这样。GetMainModuleFileName有助于从x86访问x64进程。
[DllImport("kernel32.dll")]
public static extern bool QueryFullProcessImageName(IntPtr hprocess, int dwFlags, StringBuilder lpExeName, out int size);
private bool CheckRunningProcess(string processName, string path) {
var processes = Process.GetProcessesByName(processName);
foreach(var process in processes) {
var name = GetMainModuleFileName(process);
if(name == null)
continue;
if(string.Equals(name, path, StringComparison.InvariantCultureIgnoreCase))
return true;
}
return false;
}
// Get x64 process module name from x86 process
private static string GetMainModuleFileName(Process process, int buffer = 1024) {
var fileNameBuilder = new StringBuilder(buffer);
int bufferLength = fileNameBuilder.Capacity + 1;
return QueryFullProcessImageName(process.Handle, 0, fileNameBuilder, out bufferLength)
? fileNameBuilder.ToString()
: null;
}
System.Reflection.Assembly.GetEntryAssembly()
这将为您提供有关入口程序集的大量信息,例如:
System.Reflection.Assembly.GetEntryAssembly().CodeBase;
这将告诉您正在运行的程序集的位置。
..StartsWith(new FileInfo(Application.ExecutablePath).DirectoryName)
这样的代码将无法正常工作。这是因为 DirectoryName 返回的路径会使用小写驱动器字母,例如 **c:**。因此,最好将其修改为..FileName.ToLower()
和..StartsWith(@path.ToLower())
。 - Robin Rye.StartsWith(path, StringComparison.InvariantCultureIgnoreCase)
),因为这样不会改变字符串。 - Ben
