AntiXSS v4.0中Sanitizer.GetSafeHtmlFragment等方法將部分漢字編碼爲亂碼的解決方案

AntiXSS v4.0中Sanitizer.GetSafeHtmlFragment等方法將部分漢字編碼爲亂碼的解決方案

如下代碼爲asp.net環境下,c#語言編寫的解決方案.
數據用Dictionary,而不是用其餘的例如ArrayList存放,是爲了速度.
將Dictionary替換爲HashTable也是一個不錯的解決方案
調用舉例

String abc = //....你的某些賦值行爲,這裏的字符串是要處理的內容
.............
abc=Sanitizer.GetSafeHtmlFragment(abc);//被AntiXSS處理
abc=hfjString_SanitizerCompatibleWithChineseCharacters(abc);//使之漢字不出現亂碼
