Business Process C# : Identifier expected

Hello

In a task script, you're not allowed to add the using statements.
Also, the script must end with:
return true;

You can add the using statements at the Methods block in the BP.

Hope this helps!

Mohamed Ouederni,

Hello Mohamed,
Thank you for your help ! i m a newbie in C#.

So i followed your recommandations:

i removed the using System.Text.RegularExpressions; at the script beginning, because when i open the process source code there is allready a using System.Text

i added a return true at the end of the script.

and i added too System.Text.RegularExpressions on the formatInput string :

string formatInput = System.Text.RegularExpressions.Regex.Replace(siretNumber, "[^a-zA-Z0-9_]+", "", System.Text.RegularExpressions.RegexOptions.Compiled);

But now i have the following errors:

Line 65 is :
string reverseCard = new string(formatInput.ToCharArray().Reverse().ToArray());
 

Hello,

You can add using statement in Usings section in Methods block Of BP like this:

Also here is the fixed example of your code without compilation errors:

string siretNumber = Get<String>("siret");
bool siretValide = Get<bool>("siretValide");

int ttlAddition = 0, cpt = 1;

string formatInput = Regex.Replace(siretNumber, "[^a-zA-Z0-9_]+", "", RegexOptions.Compiled);
var formatInputCharArray = formatInput.ToCharArray();
Array.Reverse(formatInputCharArray);
string reverseCard = new string(formatInputCharArray);

int[] arrDigits = Array.ConvertAll<string, int>(
   System.Text.RegularExpressions.Regex.Split(reverseCard.ToString(), @"(?!^)(?!$)"),
   str => int.Parse(str)
);
int[] arrMult = new int[arrDigits.Length];

// First Luhn step:
// Start with the last digit (on the right)
// and move to the left, doubling the value of all even-numbered digits
for (int i = 0; i < arrDigits.Length; i++)
{
	if (cpt == 1)
		arrMult[i] = arrDigits[i]; // the key is processed first, the number is not doubled 
	else
	{
		if (cpt % 2 == 0)
			arrMult[i] = 2 * arrDigits[i];
		else
			arrMult[i] = arrDigits[i];
	}
	cpt++;
}

// Add together all the digits of each number thus obtained.
// If digit > 10, then the digit to be added gives, for example: 18 = 1 + 8
for (int i = 0; i < arrMult.Length; i++)
{
	if ((int)arrMult[i] >= 10) // if number > 9 you have to break down the number, e.g. 18 gives: 1+8
	{
		int[] intList = Array.ConvertAll<string, int>(
           System.Text.RegularExpressions.Regex.Split(arrMult[i].ToString(), @"(?!^)(?!$)"),
           str => int.Parse(str)
       );
		for (int j = 0; j < intList.Length; j++)
		{
			ttlAddition += (int)intList[j];
		}
	}
	else
		ttlAddition += (int)arrMult[i];
}

// if modulo by 10 of the addition is zero then our figure is valid 
if (ttlAddition % 10 == 0)
	Set<bool>("siretValide", true); // set the variable siretValide to true in Creatio 
else
	Set<bool>("siretValide", false);
return true;

Also please make sure that "siret" and "siretValide" parameters have the values assigned before this Script Task is executed. 

Hello Iryna !
This fixed the two first errors.

it looks like system can not find Count, so i added System.link to the method block of the BP and the process has been successfully compiled.

Thank you all for you help !
