使用ICSharpCode.SharpZLib，讀取Tar.gz壓縮包的檔案名稱亂碼問題

預設版本的庫檔案讀取時會將tar包中的中文路徑讀成亂碼，兩種方案， 第一種方法，不改SharpZLib的原始碼，將讀出的Entry名稱進行如下轉換：private
string ParseName(string source){byte[] sourceByte =
new byte[source.Length];for (int i = 0; i < source.Length; i++){sourceByte[i] = (byte)source[i];}return
Encoding.Default.GetString(sourceByte);

}  即可將其轉化為正常，註：SharpZLib中，是將byte[]數組中的每一個元素強制轉化為char，然後再拼成string，所以會出現亂碼，這裡的處理是將其恢複原來的byte[]數組，再使用gb2312的編碼解出來，得到中文   第二種方法，修改SharpZLib的原始碼（有風險，未詳細測試）將TarHeader.cs中的ParseName函數改為下文所示，可解決這一問題： static
public String ParseName(byte[] header,
int offset, int length)        {            if ( header ==
null ) {                throw
new ArgumentNullException("header");            }            if ( offset < 0 ) {#if NETCF_1_0                throw new ArgumentOutOfRangeException("offset");#else                throw
new ArgumentOutOfRangeException("offset",
"Cannot be less than zero");#endif                            }            if ( length < 0 )            {#if NETCF_1_0                throw new ArgumentOutOfRangeException("length");#else                throw
new ArgumentOutOfRangeException("length",
"Cannot be less than zero");#endif                            }            if ( offset + length > header.Length )            {                throw
new ArgumentException("Exceeds header size",
"length");            }//StringBuilder result = new StringBuilder(length);            //for (int i = offset; i < offset + length; ++i) {// if (header[i] == 0) {// break;// }// result.Append((char)header[i]);//}            //return result;int tmpCount = 0;for (int i = offset; i < offset + length; ++i){if (header[i] == 0){break;}else tmpCount++;}byte[] bytes =
new byte[tmpCount];for (int i = offset; i < offset+tmpCount; i++){bytes[i] = header[i]; }string res = System.Text.Encoding.Default.GetString(bytes);return res;
