C# code that trigger on a specific subject and if the sender is a member of a group (Exchange/M365)

Here is an example of C# code if you need to create a rule in Crossware console for Exchange or M365, which will trigger a signature for 2 criteria: a specific string at the beginning of the subject (ie: subject starts with [P]) and checks if the sender is a member of a group.

See below the C# code:

List < string > lSubject;
bool bMember;
string strSubject;
string strTest = "";
string strCheck = "[P]";
bMember = (!groupmember group = "CW-Test"
 name = "(!username!)"!);
if (bMember) {
 if (pEmailHeaders.ContainsKey("subject")) {
 lSubject = pEmailHeaders["subject"];
 strSubject = lSubject[0];
 if (strSubject.Length > 3) {
 strTest = strSubject.Substring(0, 3);
 }
 if (strTest == strCheck) {
 lSubject[0] = strSubject.Substring(strCheck.Length, strSubject.Length - strCheck.Length);
 pEmailHeaders["subject"] = lSubject;
 return true;
 }
 }
}
return false;
