C# 如何获取web服务的状态

如何使用C#获取web服务的状态？它是成功完成的、失败的还是像这样挂起的。

首先我发现了这个问题

你应该试试这个代码

System.ServiceProcess.ServiceController sc = new System.ServiceProcess.ServiceController("myService");
return sc.Status

public static string PingHost(string args)  
        {  
            HttpWebResponse res = null;  

            try 
            {  
                // Create a request to the passed URI.  
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(args);  
                req.Credentials = CredentialCache.DefaultNetworkCredentials;  

                // Get the response object.  
                res = (HttpWebResponse)req.GetResponse();  

                return "Service Up";  
            }  
            catch (Exception e)  
            {  
                MessageBox.Show("Source : " + e.Source, "Exception Source", MessageBoxButtons.OK);  
                MessageBox.Show("Message : " + e.Message, "Exception Message", MessageBoxButtons.OK);  
                return "Host Unavailable";  
            }  
        } 

你应该检查这个代码

System.ServiceProcess.ServiceController sc = new System.ServiceProcess.ServiceController("myService");
return sc.Status

public static string PingHost(string args)  
        {  
            HttpWebResponse res = null;  

            try 
            {  
                // Create a request to the passed URI.  
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(args);  
                req.Credentials = CredentialCache.DefaultNetworkCredentials;  

                // Get the response object.  
                res = (HttpWebResponse)req.GetResponse();  

                return "Service Up";  
            }  
            catch (Exception e)  
            {  
                MessageBox.Show("Source : " + e.Source, "Exception Source", MessageBoxButtons.OK);  
                MessageBox.Show("Message : " + e.Message, "Exception Message", MessageBoxButtons.OK);  
                return "Host Unavailable";  
            }  
        } 

你也应该看看

如果您在同步模式下调用Web服务，则获取状态没有问题

---

如果在异步模式下调用Web服务，则应设置回调函数，并在返回给该回调函数的结果中跟踪Web服务状态。

我尝试了您的解决方案，但出现异常-在计算机“computername”上未找到服务“myservice”。

private void button1_Click(object sender, EventArgs e)
    {


        var url = "servicsURL";

        try
        {
            var myRequest = (HttpWebRequest)WebRequest.Create(url);
            NetworkCredential networkCredential = new NetworkCredential("UserName", "password","domain");
            // Associate the 'NetworkCredential' object with the 'WebRequest' object.
            myRequest.Credentials = networkCredential;
            var response = (HttpWebResponse)myRequest.GetResponse();
            if (response.StatusCode == HttpStatusCode.OK)
            {
                //  it's at least in some way responsive
                //  but may be internally broken
                //  as you could find out if you called one of the methods for real
                MessageBox.Show(string.Format("{0} Available", url));
            }
            else
            {
                //  well, at least it returned...
                MessageBox.Show(string.Format("{0} Returned, but with status: {1}", url, response.StatusDescription));
            }
        }
        catch (Exception ex)
        {
            //  not available at all, for some reason
            MessageBox.Show(string.Format("{0} unavailable: {1}", url, ex.Message));
        }

    }
