c# - Modifying the string list using reflection -

say, have class user has (string firstname, list siblings) want modify properties of user.

let's assume want replace strings b instead of a.

user : { firstname: "rager", siblings : { "stalin", "marx" } }

using reflection need read individual strings , following output object.

user : { firstname: "rbger", siblings : { "stblin", "mbrx" } }

let's consider below function

private object modifyobject(object t){    foreach(var propertyinfo in t.gettype.getproperties(){       var stringtobemodified = propertyinfo.getvalue(t,null);       propertyinfo.setvalue(t, stringtobemodified.replace("a","b"),null)    } } 

the above code works fine when modifying firstname. dont know how modify strings in siblings.

i thought make use of 3rd property (optional index value indexed properties). looks whole property not indexed. siblings, propertyinfo.getvalue(t,null) gives 2 strings.

[0] -- stalin [1]  -- marx.  

can tell me how can modify above 2 strings after getting value using propertyinfo.getvalue(t,null)?

you can cast value list<string> , update desired

eg

list<string> list = (list<string>)propertyinfo.getvalue(t,null); list[0] = list[0].replace("a","b"); 

above sample assuming propertyinfo of siblings of type list<string>, may adjust needed.
