Represents a 32-bit unsigned integer.
Assembly: mscorlib (in mscorlib.dll)
The UInt32 value type represents unsigned integers with values ranging from 0 to 4,294,967,295.
The type is not CLS-compliant. The CLS-compliant alternative type is Int64. Int32 can be used instead to replace a value that ranges from zero to MaxValue. For more information about CLS compliance, see Common Language Specification.
UInt32 provides methods to compare instances of this type, convert the value of an instance to its String representation, and convert the String representation of a number to an instance of this type.
This type implements interfaces IComparable, IComparable<T>, IFormattable, and IConvertible. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.
All members of this type are thread safe. Members that appear to modify instance state actually return a new instance initialized with the new value. As with any other type, reading and writing to a shared variable that contains an instance of this type must be protected by a lock to guarantee thread safety.
