StringComparer.GetHashCode Method (Object)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

When overridden in a derived class, gets the hash code for the specified object.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Function GetHashCode ( _
    obj As Object _
) As Integer

public int GetHashCode(
    Object obj
)

Parameters

Return Value

Type: System.Int32
A 32-bit signed hash code calculated from the value of the obj parameter.

IEqualityComparer.GetHashCode(Object)

Exceptions

Exception Condition
ArgumentException

Not enough memory is available to allocate the buffer required to compute the hash code.
ArgumentNullException

obj is nulla null reference (Nothing in Visual Basic).

Remarks
