c#定义结构体不能用？

Question

class xx｛public static struct date{string mname;string mpass;}class memory{public static date[] creatmemory(){date[] mymemory =new date[10];return mymemory;}public static void writememory(date[] m,string na,string pa){ m.mname = na;m.mpass = pa;}}提示不包含定义，或using引用

Answer 1

m 是date[] 下面这么调用出问题了
m.mname = na;
m.mpass = pa;

修改成下面的
class xx
{
public struct date
{
public string mname;
public string mpass;
}
class memory
{
public static date[] creatmemory()
{
date[] mymemory = new date[10];
return mymemory;
}

public static void writememory(date[] m, string na, string pa)
{
for (var i = 0; i < m.Length; i++)
{
m[i].mname = na;
m[i].mpass = pa;
}
}
}
}
