Net decode base6411/25/2023 ![]() Represents each Unicode code point as a sequence of one to four bytes. Consequently, you should use UTF-8 instead of UTF-7 if possible. For sequences that include non-ASCII characters, UTF-7 requires more space than UTF-8, and encoding/decoding is slower. In other cases, different UTF-7 strings can encode the same text. In some cases, changing one bit can radically alter the interpretation of an entire UTF-7 string. ![]() However, UTF-7 is not particularly secure or robust. UTF-7 supports protocols such as email and newsgroup. Non-ASCII Unicode characters are represented by an escape sequence of ASCII characters. Represents characters as sequences of 7-bit ASCII characters. Because this encoding only supports character values from U+0000 through U+007F, in most cases it is inadequate for internationalized applications. Encoding classĮncodes a limited range of characters by using the lower seven bits of a byte. NET by calling the Encoding.GetEncodings method.NET supports the character encoding schemes listed in the following table. You can retrieve information about all the encodings available in. Overloads let you specify a fallback object for both the encoder and the decoder. For more information, see Best-fit fallback.Ĭall the Encoding.GetEncoding method, which returns any standard, code page, or DBCS encoding available in. Standard encoding objects use replacement fallback, and code page and double-byte character set (DBCS) encoding objects use best-fit fallback to handle strings that they cannot encode and bytes that they cannot decode. For more information, see Replacement fallback and Exception fallback.Ĭall the Encoding(Int32) constructor and pass it an integer that represents the encoding. By default, each object uses replacement fallback to handle strings that it cannot encode and bytes that it cannot decode, but you can specify that an exception should be thrown instead. Objects for the ASCII, UTF-7, UTF-8, UTF-16, and UTF-32 encodings can be instantiated in this way. For more information, see Replacement fallback.Ĭall the encoding's class constructor. Each object uses replacement fallback to handle strings that it cannot encode and bytes that it cannot decode. ![]() For example, the Encoding.Unicode property returns a UnicodeEncoding object. Use the static properties of the Encoding class, which return objects that represent the standard character encodings available in. To access the individual encoding objects implemented in. NET inherit from the class, which is an abstract class that defines the functionality common to all character encodings. To convert binary data to a string form, use the Convert.ToBase64String method.Īll character encoding classes in. Depending on the encoding used, converting binary data to string format with the encoding classes can introduce unexpected behavior and produce inaccurate or corrupted data. They should not be used to store binary data in string form. NET encoding classes provide a way to store and convert character data.
