关于字符数组转换成整形赋值给整形数组

急!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

string name = "Hello";

int [ ] num = new int [5];

foreach(char j in name)

{

for(int i=0;i<num.length;++i)

{

num[i] = (int)j;

}

}

foreach(int i in num)

{

Console.write(i+" ");

}

我知道这个不对,请问我想达到这个效果该怎么写?非常感谢您.

string[] name = "Hello";

byte[] num = ASCIIEncoding.ASCII.GetBytes(name);
