C ++ SNAP库将std :: string转换为TStr

Question

In the SNAP Library there's a method that allows me to save a file in my pc here it is:

TSnap::SaveEdgeList(G, q, "Edge list format");`

in this function the 2nd argument its type is TStr which represents string types in SNAP library

I have a string variable that contains a full directory of where I want to put my file like this:

string filedir = openFileDialog1->FileName;

What I want to do is to give the content of a string variable to a TStr variable like this:

TStr q = filedir;

But unfortunately it gives an error. So i was wondering if anyone has an alternative solution or something Thank you

Answer 1

Quick googling revealed that TStr can be constructed from a C-string via TStr(const char* CStr) constructor.

So, following will work:

TStr q = filedir.c_str();

Alternatively, you can pass filedir.c_str() directly as an argument.
