This will generate code to decorate methods with anything you want ( stopwatch, logging , authorization…)
The code that you start with is
[AutoMethods(template =TemplateMethod.CustomTemplateFile,MethodPrefix ="prv" ,CustomTemplateFileName ="MethodDecorator.txt")]
public partial class Person
{
public string FirstName{ get; set; }
public string LastName { get; set; }
private string prvFullName()
{
return FirstName + " " + LastName;
}
}
The code that you will use is
var p = new Person();
p.FirstName = "Andrei";
p.LastName = "Ignat";
Console.WriteLine(p.FullName());
The code that is generated is
[GeneratedCode("AOPMethods", "2021.2.22.1125")]
[CompilerGenerated]
public partial class Person{
public string FullName (
[CallerMemberName] string memberName = "",
[CallerFilePath] string sourceFilePath = "",
[CallerLineNumber] int sourceLineNumber = 0){
var sw=Stopwatch.StartNew();
try{
Console.WriteLine("--prvFullName start ");
Console.WriteLine("called from class :"+memberName );
Console.WriteLine("called from file :"+sourceFilePath );
Console.WriteLine("called from line :"+sourceLineNumber );
prvFullName();
}
catch(Exception ex){
Console.WriteLine("error in prvFullName:" + ex.Message);
throw;
}
finally{
Console.WriteLine($"--------prvFullName end in {sw.Elapsed.TotalMilliseconds}");
}
}//end FullName
}
