AutoCAD Customization: .NET: How to find the section view names from the drawing

Hi all, I need to change the section view name height..I can able to collect all the text and also able to change the height.

But only for the view names i need to change the height.Im using COM API...here is my code.Thanks in advance

//why i used 3 here is ,because section view name strings  will be like" A-A"

//im also try to assign color for the view name
                   if (acadText.EntityName.Length.Equals(3))
                   {
                      
                       acadText.Height = 6.0;
                       AcadAcCmColor sectionViewTextColor = acadText.TrueColor;
                       sectionViewTextColor.ColorIndex = AcColor.acMagenta;
                       acadText.TrueColor = sectionViewTextColor;
                       acadText.update();

                   }

I dont know how to use split command,what are the arguments to pass for that
