Get Content-Disposition parameters in C#

To get the parameters of a Content-Disposition header in C#, you can use the ContentDisposition class in the System.Net.Mime namespace. Here's an example:

using System.Net.Mime;

string contentDisposition = "attachment; filename=example.txt; size=1234";

ContentDisposition disposition = new ContentDisposition(contentDisposition);

string filename = disposition.FileName; // "example.txt"
string size = disposition.Parameters["size"]; // "1234"

In this example, we have a string variable called contentDisposition with a value of "attachment; filename=example.txt; size=1234". We create a new ContentDisposition object using this value.

We can then access the FileName property of the ContentDisposition object to get the filename ("example.txt" in this case). We can also access the Parameters property, which is a NameValueCollection that contains the parameters of the Content-Disposition header. We can use the [] operator to get the value of a specific parameter ("size" in this case).

By using the ContentDisposition class in the System.Net.Mime namespace, you can easily parse the parameters of a Content-Disposition header in C#.

           string contentDisposition = "attachment; filename=file.txt";
           ContentDispositionHeaderValue disposition = ContentDispositionHeaderValue.Parse(contentDisposition);
   
           string fileName = disposition.FileName;
           Console.WriteLine("File Name: " + fileName);
       }
