Question

我在ASP.NET中有一个简单的Web服务，但Web方法需要5个参数。有没有其他方法来传递参数？像数组还是列表？我想将其限制为3.

我尝试了SetMethod（字符串参数）和dint工作。

感谢。

Answer 1

为什么不创建一个具有这些参数作为其属性的类，然后将该类的实例作为参数传递给Web方法。

改变这样的事情..

[WebMethod]
public void SomeMethod(string param1, string param2, string param3)
{
    //some code
}

这样的事情......

[WebMethod]
public void SomeMethod(SomeClass myClass)
{
    //some code
}

public class SomeClass
{
    public string Param1 { get; set; }
    public string Param2 { get; set; }
    public string Param3 { get; set; }
}

你会像这样使用它......

SomeClass myClass = new SomeClass();
myClass.Param1 = "some data";
myClass.Param2 = "more data";
myClass.Param3 = "even more";

// make the webservice call
someObject.SomeMethod(myClass);

    List<Student> list = new List<Student>();
    [WebMethod]
    public string InsertUserDetails(Student  userInfo)
    { 
        list.Add(userInfo);
        //string Message;
        SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=Sample;Integrated Security=True");
        con.Open();
        foreach (Student s in list)
        {
            SqlCommand cmd = new SqlCommand("insert into userdetail(username,password,country,email) values(@UserName,@Password,@Country,@Email)", con);
            cmd.Parameters.AddWithValue("@UserName", userInfo.UserName);
            cmd.Parameters.AddWithValue("@Password", userInfo.Password);
            cmd.Parameters.AddWithValue("@Country", userInfo.Country);
            cmd.Parameters.AddWithValue("@Email", userInfo.Email);

            int result = cmd.ExecuteNonQuery();
        }

            //if (result == 1)
            //{
            //    Message = userInfo.UserName + " Details inserted successfully";
            //}
            //else
            //{
            //    Message = userInfo.UserName + " Details not inserted successfully";
            //}
            //con.Close();

           // return Message;
        return "done";

    }

你可以这样做＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;＆gt;
