我试图在我提出的新类别中采用一种方法......

public void CalcDrinks(bool HealthOption) 
{
    if (HealthOption)
    {
        CostOfBeverage = 5M; 
    }
    else
    {
        CostOfBeverage = 20M; 
    }
}

而且,我仍然getting笑地getting着一句空话...... “预期的阶级、代表、 en、接口或结构错误”

我不敢肯定我失踪了......

最佳回答

保证该方法属于一个类别,并且该方法前后的等级/财产/其他方法的分位。 还确保先前的声明有<条码>;

这个问题通常会发生,因为你在方法之前有错配薄膜,或者你有失踪的半殖民地:

Correct

namespace A
{
    public class AA
    {
        public string B {get; set; }    
        public string C {get; set; }
        public void ShowD()
        {
            DoSomething;
        }

    }
}

Incorrect

namespace A
{
    public class AA
    {
        public string B { get; set; }      
        public string C {get; set;    // <--Note missing brace)
        public void ShowD()
        {
            DoSomething;
        }

    }
}
问题回答

如果某类方法被宣布为outside,那么你就会发现这一错误。

namespace Blah
{
    public void CalcDrinks(bool HealthOption) 
    {
        if (HealthOption)
        {
            CostOfBeverage = 5M; 
        }
        else
        {
            CostOfBeverage = 20M; 
        }
    }
}

在座标中,没有阶级定义。 摘录如下。

public class Foo
{
    private decimal CostOfBeverage;

    public void CalcDrinks(bool HealthOption)
    {
        if (HealthOption)
        {
            CostOfBeverage = 5M;
        }
        else
        {
            CostOfBeverage = 20M;
        }
    }
}

你在你的样本中找不到一些代码,但根据错误信息,你的职责是在你的班子之外宣布的。 您的方法守则必须在您的班子内公布。
