编译C#代码时出错 [英] error compiling c# code

问题描述

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace SilverlightTest.Web
{
    public class wcfSpecialLoansImplementation
    {
        SpecialLoansDataContext  db = new SpecialLoansDataContext();
        object specialLoans = from specialLoan in db.SPECIAL_LOAN select specialLoan;
    }
}

这是我用来尝试使用linq从我的名为SpecialLoans的sqlserver表中获取数据的代码.如示例所示，我已经创建了一个名为SpecialLoans.dbml的linq实体类.代码无法编译，这导致db.SPECIAL_LOAN节出现问题.它说:字段初始化程序无法引用非静态字段，方法或属性SilverlightTest.Web.wcfSpecialLoansImplementation.db''
我在做什么错?

this is the code i use to try to use linq to get data from my sqlserver table called SpecialLoans. I have created a linq entity class called SpecialLoans.dbml as seen in an example. the code wont compile cause something seem to be wrong with the section db.SPECIAL_LOAN. it says : A field initializer cannot reference the non-static field, method, or property SilverlightTest.Web.wcfSpecialLoansImplementation.db''
what am i doing wrong?

推荐答案

尝试将db和specialLoans的初始化放入构造函数中.

Try putting the initialization of db and specialLoans into the constructor.

public class wcfSpecialLoansImplementation
{
    SpecialLoansDataContext  db;
    object specialLoans;

    public wcfSpecialLoansImplementation
    {
        db = new SpecialLoansDataContext();
        specialLoans = from specialLoan in db.SPECIAL_LOAN select specialLoan;
    }
}
