如何通过网络服务访问类. [英] how to acessing a class throuth webservices.

问题描述

我有一门课程

i have a class course

public static class Course
    {
        static SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

        public static bool Updateuserdetails(string Name, string useremail, string usercont)
        {

            bool Result = false;


            try
            {
                conn.Open();

                SqlCommand cmd = new SqlCommand("Select_User_Details", conn);
                cmd.CommandType = CommandType.StoredProcedure;
                String strResult = String.Empty;
                strResult = Convert.ToString(cmd.ExecuteScalar());
                conn.Close();

                if (strResult.Length == 0)
                {
                    MessageBox.Show("Inserting new user");
                    Course.Saveuserdetails(Name, useremail, usercont);

                }
                else
                {
                    MessageBox.Show("user already exist");
                    SqlCommand cmmd = new SqlCommand("Update_user_details", conn);
                    cmmd.CommandType = CommandType.StoredProcedure;
                    cmmd.ExecuteNonQuery();


                }

我想输入Web服务..

I WANT TO PUT IN WEBSERVICES..

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [ToolboxItem(false)]  
    public  class LoginPage : System.Web.Services.WebService
    {
        [WebMethod]
       public bool insert()
        {
         Db_Helper.Course.Updateuserdetails();
         Db_Helper.Course.Saveuserdetails(Name, useremail, usercont);

但是在方法访问中显示错误....请检查它

BUT IT SHOWS AN ERROR IN ACESSING IN METHOD....PLEASE CHECK IT

推荐答案

您确定使用的是正确的方法名称，方法签名不匹配;
在课程中，您拥有；

Are you sure you are using the correct method names, the method signatures do not match;
In Course you have;

public static bool Updateuserdetails(string Name, string useremail, string usercont)

在WebService中，您拥有；

In the WebService you have;

Db_Helper.Course.Updateuserdetails();

和

and

Db_Helper.Course.Saveuserdetails(Name, useremail, usercont);

Web服务中的第二个调用是否不是 Updateuserdetails(blah blah blah)；并整理第一个.

Should the second call in the webservice not be Updateuserdetails(blah blah blah); and bin the first one.
