Source:: RandomNumberGenerator.cs

Creates a string filled with cryptographically random hexadecimal characters.

public static string GetHexString(int stringLength, bool lowercase = false);

static member GetHexString : int * bool -> string

Public Shared Function GetHexString (stringLength As Integer, Optional lowercase As Boolean = false) As String

Parameters

stringLength: Int32

The length of string to create.

lowercase: Boolean

true if the hexadecimal characters should be lowercase; false if they should be uppercase. The default is false.

Returns

String

A string populated with random hexadecimal characters.

Remarks

The behavior of this is the same as using GetString(ReadOnlySpan, Int32) and specifying hexadecimal characters as the choices. This implementation is optimized specifically for hexadecimal characters.
