How I can typecast the "0.0001 EOS" into eosio::asset

Question

I declared a variable value = "0.0001 EOS"; , inside my action I want to transfer those asset to a account .I am having difficulty to typacasting this string into the eosio::asset value . my code goes like this :

...
std::string value = "0.0001 EOS";
eosio::asset tosend = (eosio::asset)value;
...

it gives me error

 error: no matching conversion for C-style cast from 'std::string' (aka 'basic_string<char, char_traits<char>, allocator<char> >') to
     'eosio::asset'
           eosio::asset tosend = (eosio::asset)value;

if I pass the tosend value from cleos command it would work fine . so my question is can I typcast the string value into eosio::token ?

Answer 1

I find the way to solve this problem .I use the function of symbol.hpp which is located at eosiolib/symbol.hpp inside our eos . First of all I create a string and then assign some amount to the struct . My code goes like this

...
std::string sym = "EOS";
symbol_type symbolvalue = string_to_symbol(4,sym.c_str());
eosio::asset tosend;
tosend.amount = 10001;
tosend.symbol = symbolvalue;
print("tosend value is ______",tosend);
... 

so the amount here is 1.0001 EOS. it works for me . If anybody have better approach please feel free to share .
