出了点小问题,三处红波浪线.错误 1 应输入 class、delegate、enum、interface

Question

错误 1 应输入 class、delegate、enum、interface 或 struct C:\Documents and Settings\Administrator\My Documents\Visual Studio 2008\Projects\ConsoleApplication6\ConsoleApplication6\Program.cs 6 8 ConsoleApplication6程序要求：
由用户选择输出哪个形状
用户给出某个形状的大小，如正方形的边长、长方形的长和宽、三角形的高度或边长（需有一定的长度限制）
用户选择用什么符号来画，默认为“*”
选做：用户选择输出实心还是空心图形using System;

        }不能通过编译

Answer 1

最外面加上 
public class CalssName
{}
应该对了吧！试试

Answer 2

public class ［ClassName］ 
{ } ClassName 要与你的文件名同名

Answer 3

你的三个方法应该包含在某个class里面
如：
public class class1
{ 
 .
 .
 .
 static void Rectangle()
｛
 
 ｝
}
