成员'object.Equals(object，object)'不能通过实例引用进行访问；用类型名称来代替它 [英] Member 'object.Equals(object, object)' cannot be accessed with an instance reference; qualify it with a type name instead

问题描述

当我在C#中使用以下代码时...

When I used the following code in C#...

int totalValue = 0;
int total = 0;
totalValue = int.Parse(Session["price"].ToString()) * int.Parse(Session["day"].ToString());

// This line causes the error
totalValue += Session["IsChauffeurUsed"].ToString().Equals("Yes", StringComparer.CurrentCultureIgnoreCase) ? 80 : 0;

...我收到此错误:

... I received this error :

成员'object.Equals(object，object)'不能通过实例引用进行访问；而是使用类型名称来限定它.

Member 'object.Equals(object, object)' cannot be accessed with an instance reference; qualify it with a type name instead.

该错误表示什么?

推荐答案

int totalValue = 0;
int total = 0;
totalValue = int.Parse("2".ToString()) * int.Parse("2".ToString());
string s = "Yes";
totalValue += s.Equals("Yes",StringComparison.CurrentCultureIgnoreCase) ? 80 : 0;
