Regex测试器

最近在使用正则表达式，所以看着书写了个Regex测试器，忘多多吐槽

图：

具体源码如下：

using System.Collections.Generic;
using System.ComponentModel;

using System.Linq;

using System.Windows.Forms;
using System.IO;
using System.Text.RegularExpressions;
namespace Regex测试器
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
txtShowStr.ReadOnly = true;
txtInputStr.ScrollBars = ScrollBars.Vertical;
txtReplaceStr.ScrollBars = ScrollBars.Vertical;
txtShowStr.ScrollBars = ScrollBars.Vertical;
}

/// <summary>

/// </summary>

private RegexOptions getRegexOptions()
{
RegexOptions setRegexOptions =RegexOptions.None;//将RegexOptions初始值设置为None
if (this.cbECMAScript.Checked)
{
setRegexOptions |= RegexOptions.ECMAScript;
}
if (this.cbExplicitCapture.Checked)
{
setRegexOptions |= RegexOptions.ExplicitCapture;
}

{

}

{

{

}

{

}
if (this.cbSingleline.Checked)
{

}
return setRegexOptions;
