StringComparer.GetHashCode Method (String)

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 string.

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

Syntax

'Declaration
Public MustOverride Function GetHashCode ( _
    obj As String _
) As Integer

public abstract int GetHashCode(
    string obj
)

Parameters

Return Value

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

Implements

IEqualityComparer<T>.GetHashCode(T)

Exceptions

Exception Condition
ArgumentException

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

Remarks

The GetHashCode method is more efficient than the GetHashCode method because the obj parameter does not have to be unboxed to perform the operation.
