c#更改此行，使其将字符串作为变量输出

更新到POST在这段代码之后的原始帖子---这段代码是对david一直在帮助我做的事情的更新，抛出一个错误需要帮助

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.Specialized;
using System.Net;
using System.IO;


namespace ConsoleApplication1
{
    class Program
    {
    static void Main(string[] args)
    {
        string URL = "http://localhost/test2.php";
        WebClient webClient = new WebClient();

        NameValueCollection formData = new NameValueCollection();
        formData["var1"] = formData["var1"] = string.Format("MachineName: {0}", System.Environment.MachineName);
        formData["var2"] = ip();


        byte[] responseBytes = webClient.UploadValues(URL, "POST", formData);
        string responsefromserver = Encoding.UTF8.GetString(responseBytes);
        Console.WriteLine(responsefromserver);
        webClient.Dispose();
        System.Threading.Thread.Sleep(5000);
    }
    public void ip()
    {
        String publicIP = "";

        System.Net.WebRequest request = System.Net.WebRequest.Create("http://checkip.dyndns.org/");
        using (System.Net.WebResponse response = request.GetResponse())
        {
            using (System.IO.StreamReader stream = new System.IO.StreamReader(response.GetResponseStream()))
            {
                publicIP = stream.ReadToEnd();
            }
        }

        //Search for the ip in the html
        int first = publicIP.IndexOf("Address: ") + 9;
        int last = publicIP.LastIndexOf("</body>");
        publicIP = publicIP.Substring(first, last - first);

        Console.WriteLine(publicIP);
        System.Threading.Thread.Sleep(5000);


    }
}
}

this is the error I am getting 
Error   2 - An object reference is required for the non-static field, method, or property 'ConsoleApplication1.Program.ip()'
I am trying to create a function that will send the out put as var2

如何更改它，使其将字符串输出到变量（如“VAR2”）并在脚本中使用它

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.Specialized;
using System.Net;
using System.IO;


namespace ConsoleApplication1
{
class Program
{

    static void Main(string[] args)
    {
        string URL = "http://localhost/test2.php";
        WebClient webClient = new WebClient();
        NameValueCollection formData = new NameValueCollection();
        formData["var1"] = "THIS IS WHERE VAR2 NEEDS TO BE ";


        byte[] responseBytes = webClient.UploadValues(URL, "POST", formData);
        string responsefromserver = Encoding.UTF8.GetString(responseBytes);
        Console.WriteLine(responsefromserver);
        webClient.Dispose();
        System.Threading.Thread.Sleep(5000);
    }
}
}

那么，如何将机器名脚本添加到此函数，然后将其用作VAR2呢 任何帮助都会很好

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication5
{
class Program
{
    public static int Main(string[] args)
    {
        String publicIP = "";

        System.Net.WebRequest request = System.Net.WebRequest.Create("http://checkip.dyndns.org/");
        using (System.Net.WebResponse response = request.GetResponse())
        {
            using (System.IO.StreamReader stream = new System.IO.StreamReader(response.GetResponseStream()))
            {
                publicIP = stream.ReadToEnd();
            }
        }

        //Search for the ip in the html
        int first = publicIP.IndexOf("Address: ") + 9;
        int last = publicIP.LastIndexOf("</body>");
        publicIP = publicIP.Substring(first, last - first);

        Console.WriteLine(publicIP);
        System.Threading.Thread.Sleep(5000);
        return 0;
    }
}
}

为什么它需要在单独的应用程序中？如果一个应用程序的输出将成为另一个应用程序输入的命令行参数，那么它们都在同一台机器上运行。这意味着，在本例中，它们都从

System.Environment.MachineName

获得相同的值

您只需在需要的应用程序中获取值：

formData["var1"] = string.Format("MachineName: {0}", System.Environment.MachineName);

为什么它必须在单独的应用程序中？你就不能这样做：

formData[“var1”]=string.Format（“MachineName:{0}”，System.Environment.MachineName）？写下它作为我的答案，我会勾选它，因为这是我一直在寻找的ifo，我的脚本现在可以运行了：）davind你能帮我将另一个控制台应用程序集成到另一个formdat变量（如last）中吗time@user2847609：嗯，如果你有关于堆栈溢出的其他问题，那么我也许可以看一看。这与这个问题有关真的吗？我会添加其他源代码，你可以在这里再次添加答案，我会勾选它。我会立即更新我的代码。它已更新。如果你能帮助我将此脚本包含到我在c#中的其他控制台应用程序中，我会很高兴将结果输出为var2@user2847609：关于您的编辑。。。听起来你想开始做的是创建函数来计算你的值。因此，您可以创建一个单独的函数来返回结果，而不是将结果写入控制台的单独应用程序。类似于
private string CalculateSomeValue（）{//code here}
的东西，然后您可以使用以下命令调用它：
formData[“var1”]=CalculateSomeValue（）
formData["var1"] = formData["var1"] = string.Format("MachineName: {0}", System.Environment.MachineName);
formData["var2"] = "this is where this script needs to be  ";

formData["var1"] = string.Format("MachineName: {0}", System.Environment.MachineName);
