使用winforms和託管C++瀏覽文件對話框

Question

我正在第一次使用Managed C++ ...我使用Winform做了一個窗體，它有一個瀏覽文件目錄和用戶選擇的任何路徑的按鈕，路徑應該在文本框中可見。

我想知道如何在託管C++中創建文件瀏覽器對話框。

如果需要，附加表格的圖像。

您正在尋找OpenFileDialog或SaveFileDialog。

void button1_Click(Object^ /*sender*/, System::EventArgs^ /*e*/) 
     { 
      Stream^ myStream; 
      OpenFileDialog^ openFileDialog1 = gcnew OpenFileDialog; 

      openFileDialog1->InitialDirectory = "c:\\"; 
      openFileDialog1->Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"; 
      openFileDialog1->FilterIndex = 2; 
      openFileDialog1->RestoreDirectory = true; 

      if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK) 
      { 
      if ((myStream = openFileDialog1->OpenFile()) != nullptr) 
      { 
       // Insert code to read the stream here. 
       myStream->Close(); 
      } 
      } 
     }
