how can i get the StartupEventArgs

[zombers]

i have try to override the method "OnStartup",but when the StartupEventArgs.arg.length bigger than 1, my application will freeze(just can see a white page)

[zombers]

我需要双击某类型文件时，直接打开我的应用。但是我override OnStartup方法之后，只要StartupEventArgs.arg有内容 我的程序就会只弹出来一个白色页面。我不知道他卡死在哪一步了。
代码如下:
protected override void OnStartup(StartupEventArgs e)
{
if (e.Args.Length > 0){//}
base.OnStartup(e);
OnInitialized();
}

Hard to say without seeing your code. Chances are you are doing something that causes the app to not work properly. A reproduction app would go a long way in helping find the issue.

in App.xaml.cs ,I override the method "OnStartup".
when the parameter StartupEventArgs.arg length more than 0.
my application will just show me a white page.
code:
protected override void OnStartup(StartupEventArgs e)
{
if (e.Args.Length > 0){//}
base.OnStartup(e);
OnInitialized();
}

Reposting what you already posted does not help. How about a sample app the demonstrates the problem?

You don't. You have to find the issue in your code and fix it.

i konw U mean.
when exegesis the method,i can run it two way .
It seems that this method comes out of the problem

protected override void OnStartup(StartupEventArgs e)
{
if (e.Args.Length > 0)
{//save the path}
base.OnStartup(e);
OnInitialized();
}

I don't know the real use of this method

[brianlagunas]

I'm sorry, but you haven't provided any information, code, or context that anyone can use to solve your problem. The best guess I can even give is to move the call to 'base.OnStartUp()' first before the rest of the code

I'm so sorry. My English level is a little poor, which affects our communication very much. I'll give you a simplified app.xaml .cs

[zombers]

I'm sorry, but I've temporarily stopped solving this problem for work reasons. The last time I re-debugged, I found that my code wasn't working properly for other reasons, and I'll contact you when I'm free. 从 Windows 版邮件<https://go.microsoft.com/fwlink/?LinkId=550986>发送
