成员'<成员名称>'无法通过实例引用访问

Member #39;lt;member namegt;#39; cannot be accessed with an instance reference(成员lt;成员名称gt;无法通过实例引用访问)

问题描述

我正在学习 C#，但遇到了这个问题:

I am getting into C# and I am having this issue:

namespace MyDataLayer
{
    namespace Section1
    {
        public class MyClass
        {
            public class MyItem
            {
                public static string Property1{ get; set; }
            }
            public static MyItem GetItem()
            {
                MyItem theItem = new MyItem();
                theItem.Property1 = "MyValue";
                return theItem;
            }
        }
     }
 }

我在 UserControl 上有这段代码:

I have this code on a UserControl:

using MyDataLayer.Section1;

public class MyClass
{
    protected void MyMethod
    {
        MyClass.MyItem oItem = new MyClass.MyItem();
        oItem = MyClass.GetItem();
        someLiteral.Text = oItem.Property1;
    }
}

一切正常，除非我去访问 Property1.智能感知只给了我Equals、GetHashCode、GetType 和 ToString"作为选项.当我将鼠标悬停在 oItem.Property1 上时，Visual Studio 给出了这样的解释:

Everything works fine, except when I go to access Property1. The intellisense only gives me "Equals, GetHashCode, GetType, and ToString" as options. When I mouse over the oItem.Property1, Visual Studio gives me this explanation:

MemberMyDataLayer.Section1.MyClass.MyItem.Property1.get不能通过实例引用访问，而是用类型名称限定它

MemberMyDataLayer.Section1.MyClass.MyItem.Property1.getcannot be accessed with an instance reference, qualify it with a type name instead

我不确定这意味着什么，我用谷歌搜索了一些但无法弄清楚.

I am unsure of what this means, I did some googling but wasn't able to figure it out.

推荐答案

在 C# 中，与 VB.NET 和 Java 不同，您不能使用实例语法访问 static 成员.你应该这样做:

In C#, unlike VB.NET and Java, you can't access static members with instance syntax. You should do:

MyClass.MyItem.Property1

引用该属性或从 Property1 中删除 static 修饰符(这可能是您想要做的).有关 static 是，看我的其他回答.

to refer to that property or remove the static modifier from Property1 (which is what you probably want to do). For a conceptual idea about what static is, see my other answer.
