Why do websites generate random alphanumeric strings for urls instead of using row ids?


Why do websites generate random alphanumeric strings for urls instead of using row ids?

wish help you to fix your issue They are actually not random strings. Normally they are numbers (usually row IDs) that are encoded in Base-36 encoding (obviously not always the case, but there are many that use it).
Why do they use it? Because a Base-36 encoded number string is shorter than the original.

help you fix your problem How can I generate a random 8 character alphanumeric string in C#? , I heard LINQ is the new black, so here's my attempt using LINQ:
code :
private static Random random = new Random();
public static string RandomString(int length)
{
    const string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    return new string(Enumerable.Repeat(chars, length)
      .Select(s => s[random.Next(s.Length)]).ToArray());
}

this will help I am trying to generate a random code in vb.net like this , Try something like this:
code :
Public Function GetRandomString(ByVal iLength As Integer) As String
    Dim sResult As String = ""
    Dim rdm As New Random()

    For i As Integer = 1 To iLength
        sResult &= ChrW(rdm.Next(32, 126))
    Next

    Return sResult
End Function
Public Function GenerateRandomString(ByRef iLength As Integer) As String
    Dim rdm As New Random()
    Dim allowChrs() As Char = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLOMNOPQRSTUVWXYZ0123456789".ToCharArray()
    Dim sResult As String = ""

    For i As Integer = 0 To iLength - 1
        sResult += allowChrs(rdm.Next(0, allowChrs.Length))

Any of those help Note: After all these years I should point out that randomCover does not repeat. Meaning this solution will only provide a character once in lower case and once in upper case. I looked at using cycle() to remedy this but randomCover doesn't support infinite ranges.
If all you need is 32 alphnumeric characters:
code :
import std.algorithm : fill;
import std.ascii : letters, digits;
import std.conv : to;
import std.random : randomCover, rndGen;
import std.range : chain;
import std.stdio : writeln;

void main() {
    // dchar[] are random access, strings (char[]) are not
    auto asciiLetters = to!(dchar[])(letters);
    auto asciiDigits = to!(dchar[])(digits);

    dchar[32] key;
    fill(key[], randomCover(chain(asciiLetters, asciiDigits), rndGen));
    writeln(key);
}

I hope this helps . I want to uniquely identity an entity without using the primary key. So I thought about generating an unique and random value. Moreover, value must be easy to read / manually copy and is expected to be 6 or 7 characters long. , Self-answer to mark question as closed
