我有两个类,一个用于定义算法参数,另一个用于实现算法:第1类(算法参数):using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace VM_Placement{ public static class AlgorithmParameters { public static int pop_size = 100; public static double crossover_rate = 0.7; public static double mutation_rate = 0.001; public static int chromo_length = 300; public static int gene_length = 4; public static int max_allowable_generations = 400; static Random rand = new Random(); public static double random_num = rand.NextDouble(); }}第2类(实现算法):using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace VM_Placement{ public class Program { public struct chromo_typ { public string bits; public float fitness; //public chromo_typ(){ // bits = ""; // fitness = 0.0f; //} chromo_typ(string bts, float ftns) { bits = bts; fitness = ftns; } }; public static int GetRandomSeed() { byte[] bytes = new byte[4]; System.Security.Cryptography.RNGCryptoServiceProvider rng = new System.Security.Cryptography.RNGCryptoServiceProvider(); rng.GetBytes(bytes); return BitConverter.ToInt32(bytes, 0); } public string GetRandomBits() { string bits=""; for (int i = 0; i < VM_Placement.AlgorithmParameters.chromo_length; i++) { if (VM_Placement.AlgorithmParameters.random_num > 0.5f) bits += "1"; else bits += "0"; } return bits; } }}我对得到一个错误Population[i].bits = GetRandomBits();在Main()。错误是:非静态字段,方法或属性'VM_Placement.Program.GetRandomBits()'需要对象引用。我有什么想念的吗?
