首先,需要安装 Microsoft.Office.Interop.Excel
NuGet 包。
然后,可以通过以下步骤来绑定选定的一个 Excel:
- 添加命名空间:
using Microsoft.Office.Interop.Excel;
- 创建 Excel 应用程序对象和 Workbooks 对象:
var excelApp = new Application();
var workbooks = excelApp.Workbooks;
- 打开 Excel 文件:
var workbook = workbooks.Open(filePath);
- 获取选定的单元格:
var selection = excelApp.Selection;
var cellValue = selection.Value;
- 将单元格的值绑定到 WPF 的 TextBlock:
<TextBlock Text="{Binding CellValue}" />
- 创建 ViewModel 并设置 CellValue 属性:
public class ViewModel : INotifyPropertyChanged
{
private string _cellValue;
public string CellValue
{
get => _cellValue;
set
{
_cellValue = value;
OnPropertyChanged();
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
- 在窗口的代码中,将 ViewModel 与 DataContext 绑定,并设置 CellValue 属性:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = new ViewModel
{
CellValue = cellValue
};
}
private string cellValue;
private void Button_Click(object sender, RoutedEventArgs e)
{
var excelApp = new Application();
var workbooks = excelApp.Workbooks;
var workbook = workbooks.Open(filePath);
var selection = excelApp.Selection;
cellValue = selection.Value;
excelApp.Quit();
}
}
这样,当用户点击按钮后,单元格的值就会被绑定到 TextBlock 中。
