You can use the Progress object to display a Progress bar during CodeSmith code generation. This is very useful for generating time-consuming template operations. If you use Visual Studio, you can display a Progress bar in the status bar: You can use the Progress bar to set the maximum value and step size of the Progress object through the Progress attribute object of the CodeTemplate object, in this example, a simple loop is used to simulate a time-consuming operation: [csharp] <% @ Template Language = "C #" TargetLanguage = "Text" Debug = "False" %> <% @ Import Namespace = "System. threading "%> This is a progress demo. <% SimulateProgress (); %> <script runat = "template"> public void SimulateProgres S () {Progress. maximumValue = 25; Progress. step = 1; for (int I = 0; I <25; I ++) {Progress. required mstep (); Thread. sleep (100); Response. writeLine ("step {0}", I );}} </script> <% @ Template Language = "C #" TargetLanguage = "Text" Debug = "False" %> <% @ Import Namespace = "System. threading "%> This is a progress demo. <% SimulateProgress (); %> <script runat = "template"> public void SimulateProgress () {Progress. maximumV Alue = 25; Progress. step = 1; for (int I = 0; I <25; I ++) {Progress. required mstep (); Thread. sleep (100); Response. writeLine ("step {0}", I) ;}</script> the Progress bar is implemented by the PerfStep method of the SS object.
