Command可以根據CommandParameter傳參

關鍵代碼

public ICommand SubmitCommand => _submitCommand; private RelayCommand _submitCommand = new RelayCommand(new Action<object>(ShowMessage)); private static void ShowMessage(object obj) {MessageBox.Show(obj.ToString()); } <TextBox Name="textBox1"></TextBox> <Button Command="{Binding SubmitCommand}" CommandParameter="{Binding ElementName=textBox1,Path=Text}" Content="提交參數"></Button>

也可以這樣綁定

<Label Grid.Row="0">姓名：</Label> <TextBox Name="name" Grid.Row="0" Grid.Column="1" Text="{Binding Person.Name}"></TextBox> <Label Grid.Row="1">年齡：</Label> <TextBox Name="age" Grid.Row="1" Grid.Column="1" Text="{Binding Person.Age}"></TextBox> <Button Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2" Command="{Binding SubmitCommand}" CommandParameter="{Binding Person}" Content="提交參數"></Button>
