list<自定义类>排序方法

//实现接口的自定义类
//此接口规定了一个返回类型int的方法，
//public int CompareTo(object obj)
//返回1时this排object前面，0是并列，-1时this排object后面
public class varConf:IComparable
        {
            public string name;
            public string deviceType;

            public string onErrorValue;
            public string isLock;
            public byte[] bytes;

            public int CompareTo(object obj)
            {
                varConf other = obj as varConf;
                int result = 0;
                if (getValueTypeAddress(deviceAddress) > getValueTypeAddress(other.deviceAddress))

                }

List<varConf> varList = new List<varConf>();//这个是自定义类的泛型合集

varList.Sort();//按 方法中的逻辑来排序
