试图让我重定向到一个网站的按钮

Question

我想在c# WPF中创建一个登录表单但问题是，当我点击get键按钮时，我得到了一个奇怪的错误:

[! [System.Component。Win32Exception -系统找不到指定的文件[1][1]

https://media.discordapp.net/attachments/884162841974829086/897651436828123146/qPxpV.png

这是我在get键按钮代码中输入的内容:

private void GetKey_Click(object sender, RoutedEventArgs e)
{        
System.Diagnostics.Process.Start("https://pastebin.com/raw/example");
}

如果我点击查看详情，我得到这个东西:

我真的需要帮助D:

Answer 1

假设您正在使用。net Core，您可以使用以下解决方案:

System.Diagnostics.Process.Start(new ProcessStartInfo("cmd", $"/c start https://pastebin.com/raw/example") { CreateNoWindow = true });

它不能工作的原因是因为使它工作所需的调用并不是在所有平台上都能工作。

Answer 2

尝试将UseShellExecute设置为true，如下所示:

using (Process process = new Process())
{
process.StartInfo = new ProcessStartInfo
{
UseShellExecute = true,
FileName = your_url_here
};
process.Start();
}

这是因为您希望在默认的web浏览器中打开URL，而不是在执行的同一进程中打开。如果仍然不起作用，检查您的系统是否注册了默认的web浏览器。
