Question

我需要在C＃工作的人的帮助。我试图实现在URL上打开Internet Explorer的WPF应用程序，我将其作为参数补充。所以在完美的世界里，我想运行这样的东西：

 \\path\window.exe X x Y "URL" "Title"

其中X，Y是窗口的高度和宽度，URL和Title是该窗口的标题。我对C＃的了解是不存在的，所以在广泛使用google之后我设法获得了这个XAML：

<Window x:Class="WPFWebControl.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="My Web Browser" WindowState="Normal" Loaded="Window_Loaded" WindowStyle="ThreeDBorderWindow" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" Height="Auto" Width="Auto">
    <Grid>
        <WebBrowser Height="Auto" HorizontalAlignment="Left" Margin="0,28,0,0" Name="MyWebBrowser" VerticalAlignment="Top" Width="Auto" LoadCompleted="MyWebBrowser_LoadCompleted" />
        <TextBox Height="23" Margin="40,5,0,0" Name="MyTextBox" VerticalAlignment="Top" HorizontalAlignment="Left" Width="708" />
        <Button Content="Go" Margin="10,5,0,476" Name="MyGo" ToolTip="Go" Click="MyGo_Click" RenderTransformOrigin="-0.76,0.565" HorizontalAlignment="Left" Width="25" />
    </Grid>
</Window>

和这个C＃代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WPFWebControl
{    /// <summary>
     /// Interaction logic for MainWindow.xaml
     /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            try
            {
                MyWebBrowser.Source = new Uri("http://www.google.com");
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        private void MyGo_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                MyWebBrowser.Source = new Uri("http://" + MyTextBox.Text);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
        private void MyWebBrowser_LoadCompleted(object sender, NavigationEventArgs e)
        {}
    }
}

现在我需要一些建议如何通过参数设置窗口大小，网址和标题，这样我就可以摆脱那个地址文本框和按钮。

Answer 1

您可以打开一个新窗口并将WebBrowser设置为Content，例如：

WebBrowser browser = new WebBrowser();
Window win = new Window();
win.Content = browser;
win.Height = 100;
win.Width = 100;
win.Show();

win.Title = "title...";
browser.Navigate("http://google.com");

如果您希望应用程序能够接受命令行参数，则可以从StartupUri中删除App.xaml属性并覆盖OnStartup App.xaml.cs方法：

protected override void OnStartup(StartupEventArgs e)
{
    base.OnStartup(e);

    try
    {
        double width = Convert.ToDouble(e.Args[0]);
        double height = Convert.ToDouble(e.Args[1]);
        string title = e.Args[2];
        string url = e.Args[3];

        WebBrowser browser = new WebBrowser();
        Window win = new Window();
        win.Content = browser;
        win.Height = height;
        win.Width = width;
        win.Show();

        win.Title = title;
        browser.Navigate(new Uri(url, UriKind.Absolute));
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

<强>用法：

WpfApplication1.exe 100 100 "title..." "http://google.com"

Answer 2

你应该可以使用

string[] args = Environment.GetCommandLineArgs();

或者，在App.xaml中更改启动uri（删除它），然后创建自己的启动，如

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        //Manually create and show your window, passing the arguments
    }
}
