RegEx to replace string in C#

Question

I'm really not great with RegEx in C#, never really used them but I have a long string that contains a lot of html that may contain numerous text parts like

src="Folder/Uploads/fd123051-532d-4804-a0fb-fd4ce6b70f7c/cd212dd7-7600-4b3f-a7d9-9a85c85a50ca.png"

or

src="Uploads/fd123051-532d-4804-a0fb-fd4ce6b70f7c/cd212dd7-7600-4b3f-a7d9-9a85c85a50ca.png"

I want to apply a reg ex over the string if it can be done in C# so it replaces the folder path so it will change any and all to be src = filename.extension

ie.

src="Uploads/fd123051-532d-4804-a0fb-fd4ce6b70f7c/cd212dd7-7600-4b3f-a7d9-9a85c85a50ca.png"

becomes

src="cd212dd7-7600-4b3f-a7d9-9a85c85a50ca.png"

Can anyone please help?

Answer 1

RegEx for your replace:

src="Uploads/fd123051-532d-4804-a0fb-fd4ce6b70f7c/cd212dd7-7600-4b3f-a7d9-9a85c85a50ca.png"

Will be:

F: src="(.+?)//(.+?)//(.+?).png" [You can check "Dot Matches All"]

R: src="$1/$2/$3.png"  Or you can use instead of  $1 ,   /1 /2 /3 etc.

Answer 2

You need substring function that will take only the part which you want from string Please go here.

Get file name from path

Answer 3

You can use:

src = Path.GetFileName(src);
