Can you use global variables inside a t4 template? -

how can use global variables in tt file?

if declare variable in header compile error if reference in function.

<#@ template debug="false" hostspecific="false" language="c#" #> <#@ output extension=".cs" #> <#       int valueforthisfile = 35;       somefunction(); #>  <#+ void somefunction() { #>     public void generatedcode() {          int value = <#=valueforthisfile#>;     } <#+ } #> 

i know pass argument there hundreds of calls , syntactically tighter if avoid that. if 1 file hard code value there dozens of files have different settings , common include files generate code.

thanks,

i don't think possible. when t4 parses template generating class. <# #> contents injected single method on class while <#+ #> tags added methods class, allowing call them single method <# #> tags. scope of "valueforthisfile" variable limited single method. simple example, template:

<#@ template debug="false" hostspecific="false" language="c#" #> <#@ output extension=".cs" #> <#       int valueforthisfile = 35;       somefunction(); #>  <#+ void somefunction() {    return valueforthisfile; } #> 

would generate class this:

class t4gen {  private void mainwork() {     int valueforthisfile = 35;     this.somefunction(); }  private void somefunction{     return valueforthisfile; }  } 

the variable "valueforthisfile" scoped mainwork function. actual class t4 generates more complicated see there no way have global variable in code that.
