如何从按钮在WPF发送多个参数。

您只能发送一个参数为 CommandParameter 。

一个更好的解决方案通常只绑定文本框和其他控制在你的ViewModel多​​个属性。然后，命令将有机会获得所有这些属性的（因为它是在同一个班），没有必要在所有的命令参数。

How can I send multiple parameters from Button in WPF? I am able to send single parameter which is value of TextBox properly. Here is the code.

XAML

<TextBox Grid.Row="1" Height="23" HorizontalAlignment="Left" Margin="133,22,0,0"     Name="textBox1" VerticalAlignment="Top" Width="120" />
<Button Content="Button" Grid.Row="1" Height="23" Command="{Binding Path=CommandClick}" CommandParameter="{Binding Text,ElementName=textBox1}" HorizontalAlignment="Left" Margin="133,62,0,0" Name="button1" VerticalAlignment="Top" Width="75" />

Code behind

public ICommand CommandClick { get; set; }

this.CommandClick = new DelegateCommand<object>(AddAccount);

private void AddAccount(object obj)
{
    //custom logic
}

解决方案

How can i send multiple parameters from button in wpf.

You can only send one parameter as the CommandParameter.

A better solution is typically to just bind the TextBox and other controls to multiple properties in your ViewModel. The command would then have access to all of those properties (since it's in the same class), with no need for a command parameter at all.
