Play MP4 video containing special characters in file name using C# and VB.Net in ASP.Net

I maked this post as answered before when it wasnt uploading to folder with such charachters above, but now it cant play any mp4 with these charachers # - , I decided to remove those characters from the video name and it start playing, its very difficult to alow such error since i tell if users will end up uploading videos with such charachter. Bastille Day Official International Trailer #1 (2016) - Idris Elba, Richard Madden Action Movie HD The on below is without those characters and its playing but the one above is not Bastille Day Official International Trailer1 (2016) Idris Elba, Richard Madden Action Movie HD Link for the previous solved problem
