1. Paste text in the source area and click the "Encode Base64" button to encode text to Base64. The output Base64 will be listed in the target area.2. Paste Base64 in the source area and click the "Decode Base64" button to decode Base64 to text. The output text will be listed ...
public bool TryGetBytesFromBase64 (out byte[]? value); Parametri value Byte[] Se il metodo ha esito positivo, contiene la rappresentazione binaria decodificata del testo in base 64. Restituisce Boolean true se l'intero valore del token è codificato come testo valido in Base64 e può...

下列範例示範如何使用FromBase64CharArray(Char[], Int32, Int32)方法來解碼 UUencoded (base-64) 資料,並將它儲存為二進位輸出。 C# publicvoidDecodeWithCharArray(){ System.IO.StreamReader inFile;char[] base64CharArray;try{ inFile =newSystem.IO.StreamReader(inputFileName, System.Text.Encoding.ASCII...
When this method returns, contains the decoded binary representation of the Base64 text. Returns Boolean trueif the entire token value is encoded as valid Base64 text and can be successfully decoded to bytes; otherwise,false. Exceptions

Base64是一种基于64个可打印字符来表示二进制数据的表示方法。Base64常用于在通常处理文本数据的场合,表示、传输、存储一些二进制数据。包括MIME的email,email via MIME,在XML中存储复杂数据。 转换的时候,将三个byte的数据,先后放入一个24bit的缓冲区中,先来的byte占高位。数据不足3byte的话,于缓冲区中剩下的bit...
