Can anyone tell me in C# how to take a substr of a variable and compare it
to a literal ascii number.
ie:
if ( myvar.substr( 1,1 ) == 65 )
{
....
}
thanks,

One way:
if ( ASC(myvar.substr( 1,1 )) == 65 )
{
...
}

Is substr 1-based? If so:
if (myvar[0]=='A')
or
if (myvar[0]==65)

Thanks guys. What about this, will this also work?
Convert.ToChar( myvar.substr( 1, 1) ) == 65
which is the best method? as far as the fastest executing?
thanks,

Offhand yes - but its very innefficient. Jon's method is much simpler and
thus faster.

No, because there is no "substr" method. You can use Substring, but
that seems pretty pointless.

Using the indexer is faster, but more importantly it's clearer. Chances
are it's not going to be the bottleneck anyway.
