SystemUInt32

System.UInt32 is the unsigned 32-bit integer value type in the .NET framework. It is defined as a struct named UInt32 in the System namespace. In C#, the alias uint maps to System.UInt32, providing a concise keyword for this type. In VB.NET, the equivalent unsigned type is UInteger.

The type stores non-negative whole numbers from 0 to 4,294,967,295 and occupies 4 bytes of memory. As a value type, variables of this type hold the actual numeric value, and the default value is 0. System.UInt32 supports standard arithmetic and bitwise operations, and it participates in common numeric APIs. It provides parsing utilities such as UInt32.Parse and UInt32.TryParse, and supports conversion to strings via ToString.

System.UInt32 implements several common interfaces expected of .NET value types, including IComparable, IComparable<UInt32>, IEquatable<UInt32>, IFormattable, and IConvertible. These enable comparisons, equality checks, formatting, and conversions to other primitive types.

Usage considerations include the non-negative nature of the value range; negative numbers are not representable. In checked contexts, arithmetic overflow throws an exception; in unchecked contexts, results wrap around. Boxing may occur when a UInt32 value is treated as an object or as an interface type. System.UInt32 is used across .NET Framework, .NET Core, and .NET 5/6/7, and is accessible from languages targeting the common language runtime. It is a fundamental type for counts, sizes, identifiers, and other non-negative numeric data within the 32-bit unsigned range.
