converting VB asc() to C# Code

Question

I'm trying to convert the following VB code to C#

I'm stuck on the C# equivalent of VB's ASC

this

//Newstr = Newstr & chr(asc(Mid(str,x,1)) - Asc(Mid(key,KeyPos,1)))

to this

Newstr = Newstr & Convert.ToChar(asc(reverseString.Substring(x, 1)) - asc(key.Substring( KeyPos, 1)));

I assume that I converted CHR correctly.

TIA

Tim

Hi @tim , Welcome to Microsoft Q&A,

In C#, the Asc function from VB can be replaced with Convert.ToInt32(char) when working with characters, as Asc returns the ASCII (or Unicode) value of a character.

VB Code:

Newstr = Newstr & Chr(Asc(Mid(str,x,1)) - Asc(Mid(key,KeyPos,1)))

C# Conversion:

Newstr += Convert.ToChar((int)reverseString.Substring(x, 1)[0] - (int)key.Substring(KeyPos, 1)[0]);

Best Regards,
