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);

        }

    }
}
