String formatting in .NET

Anonymous — Tue, 21 Nov 2006 19:30:04 GMT

Ok, this is not really an acad-related issue, but i'm doing an Acad-net app,
so ....

In c++ i format at string with dynamic precision using the formatstring
"%.*f", m_sPrecision, x

How do i do that in .NET. I'm totally lost.

Or even better, (look; Acad related) can i format a string the same way as
using the %q formaters in ARX.
i.e. let Acad format the strings according to the unit-settings

Not sure about the C++ equivalent, but you can use
the Autodesk.AutoCAD.Runtime.Converter class in
acdbmgd.dll to convert between distance/angle and
strings.

Brilliant. Just what I wanted.

So I can fail to understand the .net string formatting for a couple of weeks
more

.NET string formatting doesn't do angles and distances,
so unless you need the more generic conversion, its not
too helpful.

"C# Text Manipulation Handbook - String Handling and Regular Expressions" by
Wrox is going to be helpful.

Microsoft has their hand in scientific computing now which should be
researched for sophisticated math and calculus capabilities. Quite possibly
the recent release of .NET 3.0 may have new classes for advanced
calculations.

If I read the last post correctly, the solution is simpler than you would first expect. You can pass formatting arguments to the ToString() method of the Double class/datatype.

Forgive the following, as I'm more used to C# than C++:

double x = 12345.67;
string s = x.ToString("N4"); //s is now "12,345.6700"

See http://msdn2.microsoft.com/en-us/library/dwhawy9k.aspx for more info.

But how do I change the 4 to a 5 depending on, for example, LUPREC ?
(ok, this has again left the autocad relationship)

On way can be to create the format string in runtime and to use that string
to format the string i wanted.
But there must be a better way! Or... ?

Look at
Autodesk.AutoCAD.DatabaseServices.Database.get_Luprec()
which returns an Int32

also, Tony refered to Autodesk.AutoCAD.Runtime.Converter class in
acdbmgd.dll
.. it's actually in acmgd.dll .. but still in the Runtime Namespace so it
will still work fine as quoted. .. no biggie.

You can dynamically format a numeric value by
defining a class that implements the IFormatProvider
interface, havin a GetFormat() member that returns
an instance of a NumberFormatInfo object, whose
members can specify formatting aspects such as the
number of decimal places, and so forth.

The converter does the job. Noprobs.
This was just a generic question on how to use the ToString("N4"); to fit my
needs.

If i unserstand it correct maybe this will help you.

int Luprec = Application.DocumentManager.MdiActiveDocument.Database.Luprec;

...

DistFPPrompt = DistFP.ToString("F" + Luprec.ToString());

DistSPPrompt = DistSP.ToString("F" + Luprec.ToString());

Dist = Math.Abs(DistSP - DistFP);

DistPrompt = Dist.ToString("F" + Luprec.ToString());

ed.WriteMessage(String.Format("\nabgewickelte Länge = {0}, erster Punkt =
{1}, zweiter Punkt = {2}", DistPrompt, DistFPPrompt, DistSPPrompt));

.NET is not simple because it utilizes an all-

Look at the String.Format() methods: it has the sprintf formatting strings you're looking for.
