I'm creating a custom template,but it confused me a long time about the syntax.I want convert a [EntityFieldName] to upper case,which key word to use? ex:

     swich(key.ToUpper())
     {
       <[Foreach EntityField CrLf]>
               case "<[EntityFieldName]>":
                   //some c# code
        <[NextForeach]>     
     }  

I hope the generated code like bellow:

     swich(key.ToUpper())
     {
               case "ENTITYFIELD1":
                   //some c# code
               case "ENTITYFIELD2":
                   //some c# code
                
     } 

Maybe I will encounter other requirements,does the llbl supply some syntax references,like chm,pdf and so on?

Here is the syntax reference. You can also download the chm from the LLBLGen Customer Area.

Unfortunately, there is no upper case modifier, just a CamelCase. You have workaround this by doing either of these:

a. Modify your generated code:

<[Foreach EntityField CrLf]>
if (key.ToUpper() == "<[EntityFieldName]>".ToUpper())
{
   // some c# code
}
<[NextForeach]>

if (key.ToUpper() == "EntityField1".ToUpper())
{
   // some c# code
}
generated code:

if (key.ToUpper() == "EntityField2".ToUpper())
{
   // some c# code
}

Not sure, but I think you still can tweak to use the switch. That is just approximate code occurs to me.

b. Use Lpt engine which is more powerful, you can do almost anything you want with templates.
