Hi I am trying to use a regular Expression to remove all line feeds from a s
tring variable in the BizTalk Mapper.

I get the following error when I compile the solution
Inline Script Error: The type or namespace name 'RegularExpressions' does no
t exist in the class or namespace 'System.Text' (are you missing an assembly
 reference?

In fact this is happening to any System.Text class I try to instanciate!!!!

My c# Inline function looks as follows

public string MyConcat(string param1)
{
return System.Text.RegularExpressions.Regex.Replace(param1, @"[^\w\.@-]"
, " ");
}

Any help would be appreciated

Regards

Adriaan

Hi Adriaan,

AFAIK this cannot be done, as you need things outside the System.* scope
and by default, the only "using" statement that's issued is "System" (this
cannot be altered or extended and is performed by
Microsoft.BizTalk.BaseFunctoids.InlineScriptCompiler).

The InlineScriptCompiler has a method called CompileScript, which is used
to compile your script into a temporary object in either implementation
language. It uses CodeDOM and wraps all scripting code for C# with,
generating a proxy dll on the fly, e.g.:

public string MyConcat(string param1)
{
return "test";
}

would become

using System;
namespace BizTalkMapper
{
public class FunctoidInlineScripts {
public string MyConcat(string param1)
{
return "test";
}

}
}

and would be compiled on the spot into an assembly by ICodeCompiler. Any
errors caused by this compilation round, is then feeded back to VS.NET.

I would implement the logic in an external assembly for re-use anyway, and
in there there's no limitation to using clauses. try this:

public string searchReplace(string input, string searchterm, string
replacement)
{
// create a regex object
Regex regex = new Regex(searchterm);

// try to perform a search/replace
string result = Regex.Replace(input, regex.ToString(),
replacement).ToString();
return result;

}

HTH,

Martijn Hoogendoorn.
