使用點符號或索引訪問DynamicModel.Query

Question

我正在使用.NET框架4.0使用Massive micro-orm和SQL Server 2008R2。

// This is my model 
    public class sUser : DynamicModel 
    { 
     public sUser() : base(Model.strConnection, "Users", "UserId") { } 
    } 

和另一類...

using System; 
    using System.Data; 
    using System.Data.SqlClient; 
    using System.Linq; 
    using System.Web; 
    using System.Xml; 
    using System.Dynamic; 
    using System.Collections.Generic; 
    using Massive; 

    public class Test 
    { 
    public dynamic GetUser(string uName) 
    { 
     dynamic table = new sUser(); 
     var objUser = table.FindBy(UserName: uName); 

     //Tried following... 
     //var objUser = new sUser().All().Where(u => u.UserName.ToString() == uName).FirstOrDefault(); 
    //var objUser = new sUser().All().Where(u => u.UserName.ToString().Equals(uName)).FirstOrDefault(); 

     return objUser; 
    } 

    public void GetSomething(dynamic testObj, string user) 
{ 
    dynamic User = GetUser(user); 

     //testObj.CUser = User["FirstName"] + ' ' + User["LastName"]; 
     //Would like to access User object like 
     //User.FirstName or User["FirstName"] 

     //And not like this... 
      foreach (var item in User) 
      { 
       testObj.CUser = item.FirstName + ' ' + item.LastName; 
      } 
} 
} 

我想訪問用戶動態對象像User.FirstName或用戶[ 「姓」]。 這是可能的，或者我錯過了什麼？

任何輸入，非常感謝。

謝謝。

你將不得不使用First方法，而不是findby

他們，你將能夠訪問這樣的屬性：

testObj.CUser = User.FirstName + User.LastName; 

全部工作的控制檯應用程序：

class Program 
{ 

    static void Main(string[] args) 
    { 
     dynamic testObj = new ExpandoObject(); 
     test t = new test(); 
     t.GetSomething(testObj, "TestUserName"); 
     Console.WriteLine(testObj.CUser); 
     Console.ReadLine(); 
    } 

} 
public class test 
{ 
    // This is my model 
    public class sUser : DynamicModel 
    { 
     public sUser() 
      : base("test", 
        "Users", 
        "UserId") { } 
    } 
    public void GetSomething(dynamic testObj, string user) 
    { 
     dynamic User = GetUser(user); 
     testObj.CUser = User.FirstName + User.LastName; 

    } 
    public dynamic GetUser(string uName) 
    { 
     dynamic table = new sUser(); 
     var objUser = table.First(UserName: uName); 

     return objUser; 
    } 
}
