How to test the length of a string in Workflow Designer

I have been programming for nearly 20 years, but I cannot figure out how to simply test the length of a string variable in Workflow Designer.  The variable I have is named sManholeID.  It has to be 6 characters long before the workflow continues.  Therefore, I am trying to set the Condition property in an If activity.  I have tried calling Len(sManholeID), Length(sManholeID), Strings.Len(sManholeID), sManholeID.Len(), sManholeID.len(), etc. and the Expression Editor isn't happy.  For equality to 6, I have tried single equal signs, double equal signs, grouping parentheses, etc.  I'm embarrassed to say that I'm stumped on this very simple expression.  Can you help me?

  Hi Roger, try sManholeID.Length()

   

  Xaml workflows use VB.Net - if you add  "VB.Net" to to a Google search, you can usually find expressions that will work for Workflow.  Eg,  "string length VB.Net" gets good Google results for this question.

  And use the Intellisense feature.

  Your expression should be something like sManholeID.Length = 6

  Thank you both.  I had been searching the internet for how to do this in VBScript, not VB.Net, so your tip was very helpful.  I had also not known about Intellisense.  I had definitely tried pressing Ctrl+Space, without knowing I had to enable something first.  As far as my question goes, there are two expressions that worked as Conditions:

   

  sManholeID.Length() = 6

   

  and

   

  sManholeID.Length = 6

   

  "Roj"
