How can I edit name of lines of layer in ArcMap from Visual Studio C#? E.g., change STR_NAME = "Pushkin street" to STREET = "Pushkin street"?

  • I'm not sure I understand your question, what is STR_NAME AND STREET (are these database column names for changing a definition query)? What do you mean by "lines of layer"? – artwork21 Oct 15 '14 at 12:04
  • If you're editing data or fields, then it's the feature class you're editing, not the layer. The layer simply points to the source data. As M.D. said below, you'll have to create a new field, copy the data, and delete the old one. – pvdev Oct 15 '14 at 15:39
  • For example, I created an add-in, a custom tool which only operates with exact layer. But it has no idea, how layer and its db columns will be named. So I desided create a options class and window, where user can set settings. Maybe renaming fields in database is a little overhead, but I research all variants. – James Tomatov Oct 16 '14 at 3:04

If you are trying to rename the field STR_NAME to STREET, ArcObjects does not allow you to do that. You will have to create the field STREET, copy the data from STR_NAME into it, then delete STR_NAME.
