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

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()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
