[C#基礎]-C# class static variable
[C#基礎]-C# class static variable測試範例
今天在爬文時，赫然發現有人在討論class static variable，馬上發揮（C/P）達人本能備份一下，有興趣的同好歡迎來（C/P）一下。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace class_static_variable
{
class static_variable
{
public static int count;
public int number;
public static_variable()
{
//count++;
number = 0;
number++;
count++;
}
public void showData()
{
Console.WriteLine("count:\t"+count);
Console.WriteLine("number:\t"+number);
int count_d = 0;//static int count_d=0;
count_d--;
Console.WriteLine("count_d:\t"+count_d);
}
//private static int pricount;
}
class Program
{
static void Main(string[] args)
{
static_variable.count = 0;
static_variable a= new static_variable();
a.showData();
static_variable b= new static_variable();
//a.showData();
b.showData();
static_variable c = new static_variable();
c.showData();
Console.ReadKey(true);
}
}
}

One thought on “[C#基礎]-C# class static variable”
剛才找到的相關資料，和大家分享
Does C# support the use of static local variables?
資料來源:http://stackoverflow.com/questions/2393156/does-c-sharp-support-the-use-of-static-local-variables
////////////////////////////////////////////////////
No, C# does not support this. You can come close with:
static System.Text.RegularExpressions.Regex re =
new System.Text.RegularExpressions.Regex("\\(copy (\\d+)\\)$");
private static string AppendCopyToFileName(string f)
{
}
The only difference here is the visibility of ‘re’. I don’t think C or Java will behave any different with regards to when this is initialized.
