You will have to create the Multivalueconveter for this:
您必须为此创建 Multivalueconveter：
Xaml:
Xml：
converter:
转换器：
<local:MyConverter x:Key="myConverter" />
Button:
按钮：
<Button>
<Button.CommandParameter>
<MultiBinding Converter="{StaticResource myConverter}">
<Binding Path="" ElementName=""/>
<Binding Path=""/>
<Binding Path=""/>
</MultiBinding>
</Button.CommandParameter>
</Button>
C#
C＃
public class MyConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return values;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
you will get the object array in the command handler.
您将在命令处理程序中获得对象数组。
Thanks
谢谢

Your question is not exactly clear, but i would think the simplest way to pass the content of your 5 textboxes to your ExecuteInsert function is to bind each of those textboxes to a property in your viewmodel class and use those properties in your function...
您的问题并不完全清楚，但我认为将 5 个文本框的内容传递给 ExecuteInsert 函数的最简单方法是将每个文本框绑定到视图模型类中的一个属性，并在您的函数中使用这些属性...
