我目前有一个 WPF 应用程序，它需要像在 ASP.NET 中一样接受来自 URL 的参数。我已经浏览了之前关于 SO 的帖子，但似乎没有什么比泥浆更清晰。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;
        }
    }
  }
}

仍然不确定您在问什么，所以我会尝试回答这两个问题。

如果“url”字段是字符串“http:\website.us?DKT_ID=param”，则可以通过使用获取字符串“DKT_ID=param”

url.Split('?')[1]

创建一个 Uri 对象除了将您的字符串解析为一个特殊对象之外不会做任何事情，如果您想执行 HTTP Get 并使用来自该 URL 的数据，请使用类似于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 ();

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，只需使用

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"];
