First create an S-function for the C-Code that you have. if you haven't deal with S-functions yet, Basic C MEX S-function will be a good start.
Once you have your C Mex S-function ready, Then Convert your .C file into a MEX file by typing MEX myfilename.C in your work space(Assuming filename as myfilename).
Then grab S-function block from your user-defined functions library in Simulink into your model. When you double click on the block it will ask you for the S-function file name and parameters that you want to pass on. In file name field give your s-function name, in this case myfilename.

Sneha have ever worked with mcc (MATLAB Compiler). In the above answer I suggested you to use MEX command to compile .C files. So if you really want to target a particular library (in your case .dll) you can do that from mcc command. if you need details on mcc check this link
