It is very good to use them to encode and decode base64. But in some case, it is a disaster. For example, if you want to encode a 4 gb file to base64, the code above must throw an OutOfMemory exception., because you must read the file into a byte array. So we need to look...
StartConvert input to byte arrayEncode byte array using Base64Encoded stringDecode string using Base64Decoded byte arrayConvert byte array to stringDecoded stringEnd 上述流程图展示了Base64.encodeBase64String方法的工作流程。首先,输入被转换为字节数组,然后使用Base64编码对字节数组进行编码得到Base64编码的字...

Returns the base64 string encoded from the bytes array. Note that byte is an integer type. Examples Kusto Copie let bytes_array = toscalar(print base64_decode_toarray("S3VzdG8=")); print decoded_base64_string = base64_encode_fromarray(bytes_array) Output Développer la table decoded...
