C#读取属性文件的类。其中，属性文件的形式应该像这样

property=value

这种情况适用于GetPropertiesText

prope=value1，value2...

这种情况适用于GetPropertiesArray

给出一个测试的例子。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
namespace CTest
{
class Program
{
static void Main(string[] args)
{
PropertyFileOperator pro = new PropertyFileOperator("test");
string[] s=pro.GetPropertiesArray("test");
foreach(string s1 in s)
Console.WriteLine(s1);

}

}
}

其中属性文件为test

内容为

test=value1,vaule2,value3

测试结果为
