输出的按说为13 可是总是67
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
public string qiuhe(String s, String s1)
{
string s2 = s + s1;
Console.WriteLine(s2);
return s2;
;
}
static void Main(string[] args)
{
Program a = new Program();
a.qiuhe("6", "7");
}
}
}
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
public string qiuhe(String s, String s1)
{
string s2 = s + s1;
Console.WriteLine(s2);
return s2;
;
}
static void Main(string[] args)
{
Program a = new Program();
a.qiuhe("6", "7");
}
}
}
你给s,s1设置的类型都是字符串型.
字符串的"+"运算是把两个字符串接起来.
那个qiuhe函数改一下.
public float qiuhe(float s, float s1)
{
float s2 = s + s1;
Console.WriteLine(s2);
return s2;
;
}
using System;
namespace ConsoleApplication1
{
/// <summary>
/// Class1 の概要の说明です。
/// </summary>
class Class1
{
public int qiuhe(int s, int s1)
{
int s2 = s + s1;
Console.WriteLine(s2);
Console.Read();
return s2;
}
[STAThread]
static void Main(string[] args)
{
Class1 a = new Class1();
a.qiuhe(6, 7);
}
}
}
