VS2013Form窗體工程應用程序開發之openFileDialog控件方式來操作打開文件對話框

1、在工程中添加openFileDialog控件：

2、修改一下控件對象的名稱，讓人感覺好像調用系統函數一樣！

3、在OpenFile這個按鈕的響應函數中示例一下：

private: System::Void btn_openFile_Click(System::Object^  sender, System::EventArgs^  e) {
	openFileDialog->Filter = "Text Files(*.txt) | *.txt";
	openFileDialog->DefaultExt = "*.txt";
	openFileDialog->InitialDirectory = System::Windows::Forms::Application::StartupPath;//起始路徑
	openFileDialog->FileName = "hi.txt"; //默認打開文件名稱
	openFileDialog->RestoreDirectory = true;
	openFileDialog->Title = "打開一個txt文件：";

	if (openFileDialog->ShowDialog() == System::Windows::Forms::DialogResult::OK){
		String ^strFilePath = openFileDialog->FileNames->GetValue(0)->ToString();//得到當前選中文件的絕對路徑
		String ^strFileName = System::IO::Path::GetFileName(openFileDialog->FileName); //獲取當前選中文件名稱
		ShowMsg(strFilePath + " " + strFileName);
	}
	else
	{
		ShowMsg("Cancled.");
	}
}
