Compares this instance to a specified object or SByte and returns an indication of their relative values.

Overloads

CompareTo(Object)	Compares this instance to a specified object and returns an indication of their relative values.
CompareTo(SByte)	Compares this instance to a specified 8-bit signed integer and returns an indication of their relative values.

CompareTo(Object)

Source:: SByte.cs

Source:: SByte.cs

Source:: SByte.cs

Compares this instance to a specified object and returns an indication of their relative values.

public:
 virtual int CompareTo(System::Object ^ obj);

public int CompareTo (object? obj);

public int CompareTo (object obj);

abstract member CompareTo : obj -> int
override this.CompareTo : obj -> int

Public Function CompareTo (obj As Object) As Integer

Parameters

obj: Object

An object to compare, or null.

Returns

Int32

A signed number indicating the relative values of this instance and obj.

Return Value	Description
Less than zero	This instance is less than `obj`.
Zero	This instance is equal to `obj`.
Greater than zero	This instance is greater than `obj`, or `obj` is `null`.

Implements

CompareTo(Object)

Exceptions

ArgumentException

obj is not an SByte.

Remarks

Any instance of SByte, regardless of its value, is considered greater than null.

The obj parameter must be null or an instance of SByte; otherwise, an exception is thrown.

Applies to

CompareTo(SByte)

Source:: SByte.cs

Source:: SByte.cs

Source:: SByte.cs

Compares this instance to a specified 8-bit signed integer and returns an indication of their relative values.

public:
 virtual int CompareTo(System::SByte value);

public int CompareTo (sbyte value);

abstract member CompareTo : sbyte -> int
override this.CompareTo : sbyte -> int

Public Function CompareTo (value As SByte) As Integer

Parameters

value: SByte

An 8-bit signed integer to compare.

Returns

Int32

A signed integer that indicates the relative order of this instance and value.

Return Value	Description
Less than zero	This instance is less than `value`.
Zero	This instance is equal to `value`.
Greater than zero	This instance is greater than `value`.

Implements

CompareTo(T)

Examples

The following example demonstrates generic and nongeneric versions of the CompareTo method for several value and reference types.

// This example demonstrates the two versions of the 
// CompareTo method for several base types.
// The general version takes a parameter of type Object, while the specific
// version takes a type-specific parameter, such as Boolean, Int32, or Double.

Remarks

This method implements the System.IComparable<T> interface and performs slightly better than the SByte.CompareTo method because it does not have to convert the value parameter to an object.

Depending on your programming language, it might be possible to code a CompareTo method where the parameter type has fewer bits (is narrower) than the instance type. This is possible because some programming languages perform an implicit widening conversion that represents the parameter as a type with as many bits as the instance.

For example, suppose the instance type is Int32 and the parameter type is Byte. The Microsoft C# compiler generates instructions to represent the value of the parameter as an Int32 object, then generates a Int32.CompareTo method that compares the values of the Int32 instance and the Int32 parameter representation.

Consult your programming language's documentation to determine if its compiler performs implicit widening conversions on numeric types.
