此方法仅返回进程文件名:
public static string GetProcessInfo(IntPtr hwnd)
{
uint pid = 0;
GetWindowThreadProcessId(hwnd, out pid);
Process proc = Process.GetProcessById((int)pid);
return proc.MainModule.FileName.ToString();
}
但我想还要返回进程名称:
proc.ProcessName;

我相信你有四个选择(按优先顺序)
proc.MainModule
并从来电者处提取必要的信息。public static ProcessModule GetProcessInfo(IntPtr hwnd) { uint pid = 0; GetWindowThreadProcessId(hwnd, out pid); Process proc = Process.GetProcessById((int)pid); return proc.MainModule; }
public class ProcessInformation { public string FileName; public string ProcessName; } public static ProcessInformation GetProcessInfo(IntPtr hwnd) { uint pid = 0; GetWindowThreadProcessId(hwnd, out pid); Process proc = Process.GetProcessById((int)pid); var pi = new ProcessInformation { proc.MainModule.FileName, proc.MainModule.ProcessName } return pi; }
Tuple<string, string>
public static Tuple<string, string> GetProcessInfo(IntPtr hwnd) { uint pid = 0; GetWindowThreadProcessId(hwnd, out pid); Process proc = Process.GetProcessById((int)pid); return return Tuple.Create(proc.MainModule.FileName,proc.MainModule.ProcessName); }
out
参数(我从未见过实施过两个参数,我不鼓励这个,因为它确实有气味,但它是C#提供的选项)string GetProcessInfo(IntPtr hwnd, out fileName, out processName)
答案 1 :(得分:5)
您可以创建并返回描述结果的对象:
public class ProcessInfo
{
public string ProcessName { get; set; }
public string FileName { get; set; }
}
public ProcessInfo GetProcessInfo(IntPtr hwnd)
{
uint pid = 0;
GetWindowThreadProcessId(hwnd, out pid);
Process proc = Process.GetProcessById((int)pid);
return new ProcessInfo
{
FileName = proc.MainModule.FileName.ToString(),
ProcessName = proc.ProcessName
}
}
或者(我个人更喜欢这个),Tuple<string, string>
:
public Tuple<string, string> GetProcessInfo(IntPtr hwnd)
{
uint pid = 0;
GetWindowThreadProcessId(hwnd, out pid);
Process proc = Process.GetProcessById((int)pid);
return Tuple.Create(proc.MainModule.FileName.ToString(),
proc.ProcessName);
}

由于两者都是string
,如何返回Tuple<string, string>
呢?
public static Tuple<string, string> GetProcessInfo(IntPtr hwnd)
{
uint pid = 0;
GetWindowThreadProcessId(hwnd, out pid);
Process proc = Process.GetProcessById((int)pid);
Tuple<string, string> t = new Tuple<string, string>
(
proc.MainModule.FileName,
proc.ProcessName
);
return t;
}

最后一个选项是使用out-params:
public voidstring GetProcessInfo(IntPtr hwnd, out string fileName, out string processName{
uint pid = 0;
GetWindowThreadProcessId(hwnd, out pid);
Process proc = Process.GetProcessById((int)pid);
fileName = proc.MainModule.FileName.ToString();
processName = proc.ProcessName;
}
答案 4 :(得分:2)
您可以将返回类型更改为Process
:
public static Process GetProcessInfo(IntPtr hwnd)
{
uint pid = 0;
GetWindowThreadProcessId(hwnd, out pid);
return Process.GetProcessById((int)pid);
}
然后从返回的对象中获取所需的数据:
var proc = GetProcessInfo(hwnd);
var processName = proc.ProcessName;
var moduleFileName = proc.MainModule.FileName.ToString();
