StringComparer.GetHashCode Method (String)

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

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

public abstract int GetHashCode(
	string obj
)

Parameters

obj
Type: System.String
A string.

Return Value

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

Implements

IEqualityComparer<T>.GetHashCode(T)

ExceptionCondition
ArgumentException

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

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