打开文件对话框并使用WPF控件和C#选择文件

我有一个名为textbox1的TextBox和一个名为button1的Button。当我点击button1时，我想浏览我的文件，只搜索图像文件（类型JPG，PNG，BMP..）。当我选择一个图像文件并在文件对话框中单击“确定”时，我希望文件目录以textbox1.text写入，如下所示：

textbox1.Text = "C:\myfolder\myimage.jpg"

Something like that should be what you need

private void button1_Click(object sender, RoutedEventArgs e)
{
// Create OpenFileDialog
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();






// Set filter for file extension and default file extension
dlg.DefaultExt = ".png";
dlg.Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif";




// Display OpenFileDialog by calling ShowDialog method
Nullable<bool> result = dlg.ShowDialog();




// Get the selected file name and display in a TextBox
if (result == true)
{
// Open document
string filename = dlg.FileName;
textBox1.Text = filename;
}
}

var ofd = new Microsoft.Win32.OpenFileDialog() {Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"}; var result = ofd.ShowDialog(); if (result == false) return; textBox1.Text = ofd.FileName;
