Question

在asp.net Web服务应用程序中将一些项目插入数据库时，我遇到了一个问题。

这是我的代码..

 public void DoRequestLog(HttpRequest request)
        {
            string UserAgent = request.Headers["User-Agent"];
            string Date = "4/14/2011";//request.Headers["Date"];
            string HostIP = request.Headers["Host"];
            string URL = request.Headers["Referer"];
            string MethodName = request.HttpMethod;
            string VersionNo = "";
            string IMEINo = "";

        string dbString = Configuration.GetDBConnectionString();

        SqlConnection DardSqlConnection = new SqlConnection(dbString);

        DardSqlConnection.Open();

        SqlCommand log = DardSqlConnection.CreateCommand();

        log.CommandText = "insert into ConnectionLog values('"+UserAgent+"','"+Date+"','"+HostIP+"','"+URL+"','"+MethodName+"','"+VersionNo+"','"+IMEINo+"');";

        log.ExecuteNonQuery();

    }

请帮助因为我是.net环境的新手。

试试这个：

public void DoRequestLog(HttpRequest request)
 {
     // We don’t need to log anything if there is no HTTP request.
     if (request == null)
         return;

     string UserAgent = request.Headers["User-Agent"];
     string Date = "4/14/2011";//request.Headers["Date"]; 
     ...

你调用的对象是空的
