在您的Web服务代码中覆盖GetWebRequest方法

例如

例如

解决方案

I found this on google (search phrase is "webservice set keepalive false") - the 2nd link among 118,000 results:

Override the GetWebRequest method in your web service code

e.g
http://weblogs.asp.net/jan/archive/2004/01/28/63771.aspx[^]



e.g
http://stackoverflow.com/questions/1527407/how-do-i-prevent-my-net-soap-client-from-including-connection-keepalive-in-th[^]

namespace YourNamespace
{
    using System.Diagnostics;
    using System.Web.Services;
    using System.ComponentModel;
    using System.Web.Services.Protocols;
    using System;
    using System.Xml.Serialization;
    /// <summary>
    /// This partial class makes it so all requests specify
    /// "Connection: Close" instead of "Connection: KeepAlive" in the HTTP headers.
    /// </summary>
    public partial class YourServiceNameWse : Microsoft.Web.Services3.WebServicesClientProtocol
    {
        protected override System.Net.WebRequest GetWebRequest(Uri uri)
        {
            System.Net.HttpWebRequest webRequest = (System.Net.HttpWebRequest)base.GetWebRequest(uri);
            webRequest.KeepAlive = false;
            return webRequest;
        }
    }
}
