Question

在 WPF 应用程序中，通过使用 c#，我希望用户能够将他们的数据导入网格视图。那么我需要一个浏览按钮还是什么？

如果是，我该怎么做？

Answer 1

以下代码可帮助您显示浏览按钮

<TextBox Height="32" HorizontalAlignment="Left" Margin="6,10,0,0" Name="FileNameTextBox"
                 VerticalAlignment="Top" Width="393" />
        <Button Content="Browse" Height="32" HorizontalAlignment="Left" Margin="405,10,0,0"
                Name="button1" VerticalAlignment="Top" Width="88" Click="button1_Click" />


// Create OpenFileDialog
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();          

// Set filter for file extension and default file extension
dlg.DefaultExt = ".txt";
dlg.Filter = "Text documents (.txt)|*.txt";

// 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;
    FileNameTextBox.Text = filename;
 }
