Definition

Important

This API is not CLS-compliant.

Represents a 64-bit unsigned integer.

Remarks

The UInt64 value type represents unsigned integers with values ranging from 0 to 18,446,744,073,709,551,615.

Important

The UInt64 type is not CLS-compliant. The CLS-compliant alternative type is Decimal. Int64 can be used instead to replace a UInt64 value that ranges from zero to MaxValue. For more information about CLS compliance, see Language Independence and Language-Independent Components.

UInt64 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.

Fields

MaxValue MaxValue MaxValue MaxValue

Represents the largest possible value of UInt64. This field is constant.

MinValue MinValue MinValue MinValue

Represents the smallest possible value of UInt64. This field is constant.

Thread Safety

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.
