Decode base64 string C# -

-

i tried decode following base64 string in c#:

pglmcmftzsbzcmm9imh0dha6ly9lbwjlzc5yzwr0dwjllmnvbs8\/awq9mzg1njamymdjb2x vcj0wmdawmdaiigzyyw1lym9yzgvypsiwiib3awr0ad0indm0iibozwlnahq9ijm0ncigc2nyb2xsaw5n psjubyigywxsb3dmdwxsc2nyzwvupjwvawzyyw1lpg==

but i'm getting error:

the input not valid base-64 string contains non-base 64  character, more 2 padding characters, or illegal character among padding characters.

even if remove last 

=

in string above still same error.

here code use:

    byte[] decodedbytes = convert.frombase64string(embedcode);     string decodedtext = encoding.utf8.getstring(decodedbytes);

why that?

thank you.

the correct base64string is:

pglmcmftzsbzcmm9imh0dha6ly9lbwjlzc5yzwr0dwjllmnvbs8/awq9mzg1njamymdjb2x vcj0wmdawmdaiigzyyw1lym9yzgvypsiwiib3awr0ad0indm0iibozwlnahq9ijm0ncigc2nyb2xsaw5n psjubyigywxsb3dmdwxsc2nyzwvupjwvawzyyw1lpg==

well not valid base64string. base64string can not have \ character. remove character , work

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()? ...
