unity插件，从一段文字中提取中文并去重

using System.Collections.Generic;
using System.Text.RegularExpressions;
using UnityEditor;
using UnityEngine;

public class ChineseCharPicker : EditorWindow
{
    string inString = "在这里输入";
    string outString = "";

    void OnGUI()
    {
        GUILayout.Label("原始内容", EditorStyles.boldLabel);
        inString = EditorGUILayout.TextArea(inString);

        GUILayout.Label("结果", EditorStyles.boldLabel);
        outString = EditorGUILayout.TextArea(outString);

        bool button = GUILayout.Button("提取", EditorStyles.miniButton);
        if (button)
        {
            Debug.Log("执行成功" + Time.time);
            convert();
        }
    }

    [MenuItem("Window/中文提取器")]
    public static void ShowWindow()
    {
        GetWindow(typeof(ChineseCharPicker));
    }


    public string pick(string str)
    {
        string rex = "[^\\一-\\龥]+";
        return Regex.Replace(str, rex, "");
    }

    public void convert()
    {
        outString = delete(pick(inString));
    }

    private string delete(string str)
    {
        char[] chars = str.ToCharArray();
        HashSet<string> result = new HashSet<string>();
        foreach (char c in chars)
        {
            result.Add("" + c);
        }

        string sb = "";
        foreach (string str1 in result)
        {
            sb += str1;
        }
        return sb;
    }
}

 

 

 

把上面代码保存为ChineseCharPicker.cs放到Assets/Editor即可
