c语言hello world代码(代码编程入门)

大家好，又见面了，我是你们的朋友全栈君。

using System;
using System.Collections.Generic;
public class MyClass
{ 

struct Name{ 

public string FirstName;
public string LastName;
public string GetName(){ 

return  FirstName + "·" + LastName; 
}
}
struct Vector3{ 

public float x;
public float y;
public float z;
public double Distance(){ 

return Math.Sqrt(x*x+ y*y+ z*z);
}
}
public static void RunSnippet()
{ 

Name myName;
myName.FirstName = "Alexander";
myName.LastName = "Azhar";
System.Console.WriteLine("My name is " + myName.GetName());
Vector3 point;
System.Console.WriteLine("Please enter three points' position to calculate its distance: ");
point.x = Convert.ToInt32(System.Console.ReadLine());
point.y = Convert.ToInt32(System.Console.ReadLine());
point.z = Convert.ToInt32(System.Console.ReadLine());
System.Console.WriteLine("The Sqrt distance of the three points is "+point.Distance()+" .");
}
#region Helper methods
public static void Main()
{ 

try
{ 

RunSnippet();
}
catch (Exception e)
{ 

string error = string.Format("---\nThe following error occurred while executing the snippet:\n{0}\n---", e.ToString());
Console.WriteLine(error);
}
finally
{ 

Console.Write("Press any key to continue...");
Console.ReadKey();
}
}
private static void WL(object text, params object[] args)
{ 

Console.WriteLine(text.ToString(), args);	
}
private static void RL()
{ 

Console.ReadLine();	
}
private static void Break() 
{ 

System.Diagnostics.Debugger.Break();
}
#endregion
}

上面代码的结构一定要记住，因为结构比较好，所以和大家分享。
