best way to evaluate what type of control there is

• RickRSL

  As Chris Vega says, you can use the is keyword to checks if an object is compatible with a given type.
  An is expression evaluates to true if the provided expression is non-null, and the provided object can be cast to the provided type without causing an exception to be thrown.
  
  

  Control control = new Label(); if( control is Label ) { // TODO: Add logic. }

  
  
  You can also use the as keyword to perform conversions between compatible reference types.
  The as operator is like a cast except that it yields null on conversion failure instead of raising an exception.
  

  Control control = new Label(); Label label = control as Label; if( label != null ) { // TODO: Use the label. } else { // control could not be casted to a Label. }

  
  
  Take a look at the Cast expressions page for more information about casting.

  Don't compare types using its string representation. Instead, you can compare types using either of these two methods:
  
  

  if (c is System.Web.UI.WebControls.Label) { // TODO: True code here... }

  
  
  Or (specific type comparison):
  
  

  if (c.GetType() == typeof(System.Web.UI.WebControls.Label)) { // TODO: True code here... }
