Xaml Parse Exception WPF

Question

I have encountered a problem with my Whack a Mole Game:

XamlParseException was unhandled

'The invocation of the constructor on type 'WhackaMoleReal.MainWindow' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'.

This is my main code:

    }

}

and my XAML:

<Window x:Name="MainWin" x:Class="WhackaMoleReal.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Image Margin="353,156,-131,-58" Source="mole2.png" Stretch="Fill"/>
        <TextBlock HorizontalAlignment="Left" Margin="20,10,0,0" TextWrapping="Wrap" Text="Can You Catch the Mole?" VerticalAlignment="Top" Height="79" Width="497" FontFamily="SimHei" FontSize="40"/>

    </Grid>
</Window>

Answer 1

Environment.GetCommandLineArgs() should return at least an array of 2 objects, since you are referring to that in your constructor

Moleini = CmdArgs[1];

I tried out your code. Environment.GetCommandLineArgs() was returning only 1 object.

Answer 2

我发现了我的问题，我只需要删除并放回.ini值获取.dll :)
