尝试在c＃中设置作为类属性的数组值时出错

Question

object reference is required for the non-static field, method, or property

我的代码中出现上述错误，我无法弄清楚原因（有许多类似的问题，但我读过的所有内容似乎都与我有关）。

class Program
{
    static void Main(string[] args)
    {

        VenueMappings venueMappings = new VenueMappings();
        var venue1 = new Venue
        {
            ExtEventNo = 1,
            UsiVenue = "building1",
        };

        VenueMappings.venues[0] = venue1;
    }
}

public struct Venue
{
    public int ExtEventNo;
    public String UsiVenue;
};


public class VenueMappings
{
    public Venue[] venues = new Venue[2];  
};

Answer 1

此处的问题是您使用的是班级名称VenueMappings，但您应该使用变量venueMappings。您可以通过类名引用静态属性和方法，但是您只能通过实例引用实例属性和方法。

替换

VenueMappings.venues[0] = venue1;

与

venueMappings.venues[0] = venue1;
