WebNov 6, 2008 · Contrary to the current most popular answer, shorter integers (like Int16 and SByte) do often times take up less space in memory than larger integers (like Int32 and Int64). You can easily verify this by instantiating large arrays of sbyte/short/int/long and using perfmon to measure managed heap sizes. WebC# public static int ToInt32 (string? value); Parameters value String A string that contains the number to convert. Returns Int32 A 32-bit signed integer that is equivalent to the number in value, or 0 (zero) if value is null. Exceptions FormatException value does not consist of an optional sign followed by a sequence of digits (0 through 9).

WebAug 22, 2024 · In C#, int is mapped to Int32. It is a value type and represent System.Int32 struct. It is signed and takes 32 bits. It has minimum -2147483648 and maximum +2147483647 capacity. Int64 It is a FCL type. In C#, long is mapped to Int64. It is a value type and represent System.Int64 struct. It is signed and takes 64 bits. WebMar 22, 2011 · Int32 corresponds to int, Int64 corresponds to long. For most general uses you can use 32-bit integers; however if you need very large numbers use long integers (64-bit). When you assign Int64.MaxValue to an int, you're implicitly converting a long ( Int64) to an int ( Int32 ), which doesn't work. ircc walk in
