C # receives multiple problems with the same name value in form forms

The value of the previously received form form is received directly from the FormCollection or custom class, and is automatically separated with "," when there are multiple values of the same name, so there is a problem, and it is more difficult to deal with the "," in the value itself.

So the solution is

string [] Txtarr = request.params.getvalues["Name"]

So you don't have to split the ","
