One is to collect all Chinese characters into a comparison table; the other is to determine the first letter of the pinyin according to the sorting of Chinese characters in the Unicode encoding table. When encountering polyphonic characters, the common ones shall be used as the basis (the first method can be changed by yourself. The method is to manually move the Chinese character to the corresponding pinyin first line queue. We will introduce the second one here

Getting the first letter of the Chinese character pinyin is a function that is often used in the process of doing projects. Today we will mainly discuss C# to get the first letter of the Chinese character pinyin

/// <summary>

/// Search the pinyin index string in the specified string list CnStr
/// </summary>

/// <param name="CnStr">Chinese character string</param>
/// <returns>The corresponding Chinese pinyin string</returns>
public static string GetSpellCode(string CnStr) {

string strTemp="";

int iLen=;

int i=0;

for (i=0;i&lt;=iLen-1;i++) {

 strTemp+=GetCharSpellCode((i,1));

}

return strTemp;

}

/// &lt;summary&gt;

/// Get the first letter of the pinyin of a Chinese character. If it is an English letter, it will directly return to the capital letter.
/// &lt;/summary&gt;
