Question

I have a button that starts uploading a filename that has Spaces.

Firefox fails to use this name, its OK for IE.

How to encode spaces to underlines with csharp?

Answer 1

The String.Replace(char, char) method, thus:

string filename = "This is an example";

string encodedFilename = filename.Replace(' ', '_');

Console.WriteLine(encodedFilename);

Produces “This_is_an_example”.
