I have created the following:

[WebMethod]
public SubjectProperty[] UpdateSubjectProperty(string _CDKey, string
_UIKey, string _Subject)
{
SubjectProperty[] _SubjectProperty =
_SearchController.UpdateSubjectProperty(_CDKey, _UIKey, _Subject);

return _SubjectProperty;

Which in turn is linked to:

public void UpdateSubjectProperty(string _CDKey, string _UIKey,
SubjectProperty _Subject)
{

}
catch(MGException mgex)
{
throw mgex;
}
catch(Exception e)
{
throw new MGException(MGException.LoggingLevelTypes.On,"Unable to update
Subject Property",e);
}

When I attempt to build the project I get the following error message:

"Argument '3' cannot convert from 'String' to
'System.InfoTools.BITTools.Search.Subject Property'." What does that mean?
 
Look at your method:

public void UpdateSubjectProperty(string _CDKey, string _UIKey,
SubjectProperty _Subject)

The error message seems to indicate that somewhere in your code you're
trying to call this method passing 3 strings. This does not match the
signature, since the method expects the third argument to be of type
System.InfoTools.BITTools.Search.Subject Property.

Take a look at all calls to this method in your code. There should be one
passing invalid parameters.
