Templating Methods

Methods

Templating supports two types of methods:

• Framework Methods
• User-Defined Methods

The syntax for invoking framework methods, and user-defined methods is the same; the difference lies in how user-defined methods are declared.

Framework Method Invocation

You can invoke framework methods within the template.

Syntax	Description
{{x => x.variable.ToUpper()}}	Invoke a framework method.

User-Defined Methods

You can define custom methods and use them within the template. User-defined methods are Action lambdas that are registerd with the template parser. (see example below).

Syntax	Description
{{x => x.CustomUpper( x.variable )}}	Invoke a user-defined method.

var options = new TemplateOptions()
    .AddVariable( "name", "me" )
    .AddMethod( "CustomUpper" ).Expression<string, string>( arg => arg.ToUpper() ) ;

var template = "hello {{x => x.CustomUpper(x.name)}}.";

var result = Template.Render(template, options);
Console.WriteLine(result); // Output: hello ME.
