我想你正在嘗試做同樣的事情,因爲我在—從當前路徑的資源管理器中打開一個shell。
我遇到了完全相同的問題。這是一個爲我工作的程序。它使用EnumWindows
來搜索所有可見的窗口,直至找到其標題爲真實路徑的人。

{

{
const int nChars = 256;
StringBuilder buffer = new StringBuilder(nChars);
IntPtr result = GetWindowLongPtr(new IntPtr(hwnd), GWL.GWL_STYLE);
// ignore invisible windows
if ((result.ToInt64() & WS_VISIBLE) != 0)
{
if (GetWindowText(hwnd, buffer, nChars) > 0)
{
string title = buffer.ToString();

EnumWindows(_callBackPtr, 0);
Process shell = new Process();
shell.StartInfo.FileName = "cmd.exe";
if (!string.IsNullOrEmpty(_folder))
shell.StartInfo.WorkingDirectory = _folder;
shell.Start();

它到目前爲止我的工作(Win7-64)。請注意,您不必直接在資源管理器窗口中工作—它將使用Tab鍵順序中的下一個。
