C# 类型或命名空间定义，或应为文件结尾。
我是C#的新手，我正在学习如何使用一本书。但是在创建这个之后（粘贴在另一个解决方案的代码中）。数学题是从另一个解决方案粘贴的，是的，我知道我不应该使用goto，但我稍后会停止。我想我有太多的“{}”，但我似乎找不到正确的区域。如果我的错误很愚蠢，请原谅C# 类型或命名空间定义，或应为文件结尾。,c#,C#,我是C#的新手，我正在学习如何使用一本书。但是在创建这个之后（粘贴在另一个解决方案的代码中）。数学题是从另一个解决方案粘贴的，是的，我知道我不应该使用goto，但我稍后会停止。我想我有太多的“{}”，但我似乎找不到正确的区域。如果我的错误很愚蠢，请原谅 using System; namespace LearningCSharp { class MainClass { public static void Main(string[] args) {
