【LABVIEW到C#】3》String的操作之Match Pattern Funtion.vi

標籤：

C#實現如下

using System;using System.Collections.Generic;using System.Text;using System.Text.RegularExpressions;namespace DEMO{    class Darrenstring    {        public class Matchpattern:Darrenstring        {            private string text;            private string pattern;            private int index;            public bool ismatch;            public Matchpattern(string Text, string Pattern)            {                text = Text;                pattern = Pattern;                Match a = Regex.Match(text,pattern);                index=a.Index;                ismatch = a.Success;            }            public int Index()            {                return index;            }            public string Before()            {                if (ismatch)                {                    return (text.Substring(0, index));                }                else return null;            }            public string After()            {                if (ismatch)                {                    return (text.Substring(index + pattern.Length, text.Length - pattern.Length-index));                }                else return null;            }        }    }}

類寫好後 我們來做個實驗 建立個winform程式 

程式部分代碼如下：

 private void Confirm_Click(object sender, EventArgs e)        {            Darrenstring.Matchpattern A = new Darrenstring.Matchpattern(Source.Text, Terminal.Text);            //Terminal.Text = Convert.ToString(A.Index());            before1.Text = A.Before();            After.Text = A.After();            IsMatched.Checked = A.ismatch;                    }

運行後結果圖如下:

效果不錯功能實現
