而且資料不夠準確+完整 所以這範例只能讓使用者
知道運行原理 下一章將會補上 "中文轉羅馬的完整程式"
首先 先在 windows 設計模式 加入 2個 textbox
一個用於輸入文字叫 txt_Chinese
一個用於輸出文字叫 txt_PinYin
為了讓使用者 在輸入時 觸發!
因次我們必須讓 txt_Chinese這控制項觸發事件為TextChanged
Ps:在設計模式中 可以點選txt_Chinese然後右下角 有一個閃電
並且挑選 需要的觸發事件 即可
因此我們就可以在每次輸入文字時 同時觸發程式!
來看程式碼吧!
private void txt_Chinese_TextChanged(object sender, EventArgs e)
{
//呼叫PinYin.cs檔的GetABC方法並且帶入使用者輸入的"字"
txt_PinYIn.Text = //呼叫拼音類的GetABC方法得到拼音字串
new PinYin().GetABC(txt_Chinese.Text);
}
當使用者開始輸入文字到txt_Chinese時將會觸發TextChanged事件
而我們由這事件的觸發 開始程序!
來看程式區塊中txt_PinYin.Text= new PinYin().GetABC(txt_Chinese.Text)
txt_PinYin.text輸出的結果
等於PinYin.cs檔案中的方法叫GetABC(?)
而GetABC(txt_Chinese.Text)
將傳送txt_Chinese.Text字串給 GetABC
接下來我們來瞧瞧使用者在txt_Chinese輸入的中文 送入GetABC(txt_Chinese)
會發生啥事
看程式碼吧
public string GetABC(string str)//str=控制項中的txt_Chinese.Text
{
//先宣告正規化 條件式驗證輸入是否為中文字
Regex reg = new Regex("^[\u4e00-\u9fa5]$");// \u4e00~\u9fa5是unicode中文範圍
byte[] arr = new byte[2];//定義2byte字 節陣列 等等要存放unicode的
string pystr = "";//定義字串變數用於返回拼音
char[] mChar = str.ToCharArray();//取得中文字對應的字符陣列unicode 16bit會轉成10進位以char呈現
return GetStr(mChar, pystr, reg, arr);//返回取得到的中文字拼音
}
其實 註解已經 很清楚了 str是txt_Chinese
首先 建構 正規化Regex 函式 並且將
而字串中的\u4e00-\u9fa5 代表unicode中文範圍
正規化 將用來比對 使用者輸入是否是個中文字
再來宣告 byte陣列 2個 待會是要將中文的big碼
16Bit已各分8bit存入 byte中
二來
string pystr 是要將最終答案的結果回傳給初始呼叫副程式的地方
三來
char[] mChar = str.ToCharArray();
char 字元陣列利用ToCharArray()取str一個字元 並且陣列存入
如果str有兩字元 講會有 兩個char陣列
最後
return GetStr(mChar, pystr, reg, arr)
return 回傳給 TextChanged事件中 呼叫的副程式
但是
return 回傳是一個GetStr副程式
所以必須將GetStr裡的程序跑完才能回傳給TextChanged事件中的
GetABC(txt_Chinese.Text)
注意看 GetStr(mChar, pystr, reg, arr)方法中帶入的參數
我們下一段將介紹GetStr中的程序
來看下面GetStr()程式碼
private string GetStr(char[] mChar, string pystr, Regex reg, byte[] arr)
{
int asc = 0, M1 = 0, M2 = 0;//宣告3個整數
for (int j = 0; j < mChar.Length; j++)//mChar.Lenth看有幾個字char
{
if (reg.IsMatch(mChar[j].ToString()))//reg正規化條件中mChar的字是否府和unicode中文字範圍內
{
//假如mChar[j] = 陳, unicode 是38515 big 是B3AF ,big碼將分成2位元組=179.175
arr = System.Text.Encoding.Default.GetBytes(mChar[j].ToString());
M1 = (short)(arr[0]);
M2 = (short)(arr[1]);
asc = M1 * 256 + M2 - 65536;
if (asc > 0 && asc < 160)
{
pystr += mChar[j];//條件相符直接印到pystr
}
else//不然 再進行選識
{
switch (asc)
{
case -9254:
pystr += "Zhen"; break;
case -8985:
pystr += "Qian"; break;
case -5463:
pystr += "Jia"; break;
case -8274:
pystr += "Ge"; break;
case -5448:
pystr += "Ga"; break;
case -5447:
pystr += "La"; break;
case -4649:
pystr += "Chen"; break;
case -5436:
pystr += "Mao"; break;
case -5213:
pystr += "Mao"; break;
case -3597:
pystr += "Die"; break;
case -5659:
pystr += "Tian"; break;
default://casw 條件不府 再進行下列 比對
for (int i = (getValue.Length - 1); i >= 0; i--)
{ //比對(getValue[i]陣列中 有無小於或等於asc
if (getValue[i] <= asc)//判斷中文字的拼音區編碼是否在指定範圍內
{
//比對成功的i值 直接對應getStr[i]中的答案 最後 印出
pystr += getStr[i];//如果不超出範圍則取得對應的拼音
break;
}
}
break;
}
}
}
else//如果不是中文字
{
pystr += mChar[j].ToString();//如果不是中文字則返回
}
}
return pystr;// 最後 回傳pystr給txt_PinYIn.Text
}
一開始 for (int j = 0; j < mChar.Length; j++)
迴圈中來判斷mChar幾個字
而if (reg.IsMatch(mChar[j].ToString()))
是使用正規化來Match判斷mChar[j]是否是一個中文字元
條件達成後
arr = System.Text.Encoding.Default.GetBytes(mChar[j].ToString());
特別說一下
arr 目前是空的將可放入2個byte 而這2byte 取自於 中文字元big碼的2byte 16bit
System.Text.Encoding是因為沒有宣告命名空間所以重系統呼叫
而Default預設編碼為DBCS 取雙位元組 而.GetBytes是放進byte[]中!
再來後面的演算法 就無需再介紹
因為這字典檔 並非一個完整的羅馬字符
下面演算法 將不停比對 陣列中的數直 是否與字典檔案相同
字典檔案如下
//定義拼音區編碼陣列
private static int[] getValue = new int[]
