c# - Passing dynamic parameters with ExpandoObject -

-

i have function prototype looks kind of this: public void dothings(string sql, dynamic dparams);

it kind of sql querying parameters. didn't write have use it. works fine when this:

dothings("select * sometable myval1=@v1 , myval2=@v2",         new         {             v1 = new dapper.dbstring()             {                 value = "yay",                 isansi = true,                 length = 50             },             v2 = new dapper.dbstring()             {                 value = "really",                 isansi = true,                 length = 32             }         });

but not when first put dynamic params expandoobject:

dynamic dynparams = new expandoobject(); dynparams.v1 = new dapper.dbstring()     {         value = "yay",         isansi = true,         length = 50     } dothings("query here", dynparams);

the query returns no results. don't want call dothings() , write new block ten times ten different scenarios might want query myval2 or myval3 , on. there special way should passing expandoobject, or other way should doing in general?

dapper doesn't support expandos default, can pass expando constructor of dictionary<string,object> , pass dynamic argument.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...
