Question

我目前有一个WPF应用程序需要接受来自URL的参数，就像在ASP.NET中一样。我已经浏览过上一篇关于SO的帖子，但似乎没有像泥一样清晰。我已经将“发布”中的部分更改为接受参数。以下是我正在使用的代码：

using System;
using System.Deployment;
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;
using ViewImageForm;
using System.Windows.Forms.Integration;
using System.Windows.Forms;
using System.Web;
using System.Collections.Specialized;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Deployment.Application;

namespace WPFHost
{
    /// <summary>
    /// Interaction logic for Page1.xaml
    /// </summary>
    public partial class Page1 : Page
    {
        private readonly Form1 mainForm = new Form1();

    public Page1()
    {
        InitializeComponent();

        //Create a Windows Forms Host to host a form
        WindowsFormsHost windowsFormsHost = new WindowsFormsHost();

        stackPanel.Width = mainForm.Width;
        stackPanel.Height = mainForm.Height;
        windowsFormsHost.Width = mainForm.Width;
        windowsFormsHost.Height = mainForm.Height;

        mainForm.TopLevel = false;

        windowsFormsHost.Child = mainForm;

        stackPanel.Children.Add(windowsFormsHost);
    }

    private void Page_Loaded(object sender, RoutedEventArgs e)
    {
        if (ApplicationDeployment.IsNetworkDeployed)
        {
        string url =
        AppDomain.CurrentDomain.SetupInformation.ActivationArguments.ActivationData[
        0];
        string queryString = (new Uri(url)).Query;
        this.textBox1.Text = queryString;
        }
    }
  }
}

仍然不确定你在问什么，所以我会尽力回答这两个问题。

如果“url”字段是字符串“http：\ website.us？DKT_ID = param”，则可以使用

获取字符串“DKT_ID = param”

url.Split('?')[1]

创建Uri对象除了将字符串解析为特殊对象之外不会执行任何操作，如果要执行HTTP Get并使用该URL中的数据，请使用类似MSDN中的示例：

        WebRequest request = WebRequest.Create (
          "http:\\website.us?DKT_ID=param");
        // If required by the server, set the credentials.
        request.Credentials = CredentialCache.DefaultCredentials;
        // Get the response.
        WebResponse response = request.GetResponse ();
        // Get the stream containing content returned by the server.
        Stream dataStream = response.GetResponseStream ();
        // Open the stream using a StreamReader for easy access.
        StreamReader reader = new StreamReader (dataStream);
        // Read the content.
        string responseFromServer = reader.ReadToEnd ();
        // Display the content.
        textBox1.Text = responseFromServer;
        // Clean up the streams and the response.
        reader.Close ();
        response.Close ();

<强>更新如果您只想要“param”字符串，并且查询字符串中不会有任何其他参数，请使用

url.Split('=')[1]

如果有多个参数，那么您需要执行类似

的操作

Dictionary<String,String> params;
string[] queryParams = url.Split('?')[1].Split('&');
foreach (string s in queryParams)
{
   string[] queryParameter = s.Split('=');
   params.Add(queryParameter[0], queryParameter[1]);
}

textBox1.Text = queryParams["DKT_ID"];

C＃将查询字符串中的参数传递给WPF应用程序
