The length of the new String is a function of the charset, and hence may not be equal to the length of the subarray. The behavior of this constructor when the given bytes are not valid in the given charset is unspecified. The CharsetDecoder class should be used when more control over ...
Retrieves an object that can iterate through the individual characters in this string. GetHashCode() Returns the hash code for this string. GetHashCode(ReadOnlySpan<Char>, StringComparison) Returns the hash code for the provided read-only character span using the specified rules. GetHashCode(Read...
Finally, don't use the hash code instead of a value returned by a cryptographic hashing function if you need a cryptographically strong hash. For cryptographic hashes, use a class derived from the System.Security.Cryptography.HashAlgorithm or System.Security.Cryptography.KeyedHashAlgorithm class. For...

C语言Redis hash数据读取 redis string hash存储量对比,我们在缓存json数据到redis时经常会面临是选择string类型还是选择hash类型去存储。接下来我从占用空间和IO两方面来分析这两种类型的优势。1、占用空间根据数据结构的共识我们知道hashtable类型是要比string类型更占用

This hash function is also appropriate for keys that are integers stored in pointers, such as GINT_TO_POINTER (n). 此哈希函数也适用于存储在指针中的整数键,例如 GINT_TO_POINTER (n)。 【INT】g_int_hash guint // A hash value corresponding to the key. ...
