问题描述

＃1 - string str =ABCDVER+1;

＃2 - string str2 =ABCDVER; string str3 =1;

＃3 - string str1 = string.format（{0} {1}，str2，str3）;



第1行和第2行给出了相同的答案？请确认。



谢谢

我是什么尝试过：



＃1 - 字符串str =ABCDVER+1;

＃2 - 字符串str2 =ABCDVER; string str3 =1;

＃3 - string str1 = string.format（{0} {1}，str2，str3）;



第1行和第2行给出了相同的答案？请确认。



谢谢

Arun

#1 - string str = "ABCDVER" + "1";
#2 - string str2 = "ABCDVER"; string str3 = "1";
#3 - string str1 = string.format("{0}{1}",str2,str3);

Line#1 and Line#2 gives same answer?. Please confirm.

Thanks
Arun

What I have tried:

#1 - string str = "ABCDVER" + "1";
#2 - string str2 = "ABCDVER"; string str3 = "1";
#3 - string str1 = string.format("{0}{1}",str2,str3);

Line#1 and Line#2 gives same answer?. Please confirm.

Thanks

推荐答案

No。

第1行和第3行给出相同的答案，因为str和str1是相同的 - 但不是1和2.



你可以解决这个问题很容易使用调试器，甚至只是编写代码：

No.
Lines 1 and 3 give the same answer in that str and str1 are the same - but not 1 and 2.

You could have solved this very easily with the debugger, or even just by writing code:

string str = "ABCDVER" + "1";
string str2 = "ABCDVER"; string str3 = "1";
string str1 = string.Format("{0}{1}", str2, str3);
if (str == str1) Console.WriteLine("Yes");
else Console.WriteLine("No");

直观地看待

see visually

class Program
{ 
    static void Main(string[] args)
    {
    string str = "ABCDVER" + "1";
    string str2 = "ABCDVER"; string str3 = "1";
    string str1 = string.Format("{0}{1}",str2,str3);
    System.Console.WriteLine(str);
    System.Console.WriteLine(str1);
    System.Console.WriteLine("is equal?: " +  (str1 == str));
    System.Console.ReadLine(); 
    } 
}
