type conversion - Convert float to std::string in C++ -

-

I have float value that should be inserted into std :: string . How do I convert from float to string? 

  float val = 2.5; Std :: string my_val = val; // error here

Unless you are concerned about performance, its Use: 

  std :: ostringstream ss; SS & lt; & Lt; MyFloat; Std :: string s (ss.str ());

If you are OK with Boost, then there is a convenient option: 

  std :: string s = boost :: lexical_cast & lt; Std :: string & gt; (MyFloat);

Efficient options eg Or just the C-style function.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
