IResource Interface IT Hit WebDAV for .NET

Represents a resource in the WebDAV repository.

For a list of all members of this type, see IResource Members.

Remarks

Defines the properties and methods that WebDAV server resource objects must implement. In addition to methods and properties provided by IHierarchyItem this interface also provides methods for reading and writing resource content. ContentType property must return the MIME type of the resource.

Example

    public class Resource : HierarchyItem, IResource
    {
        public Resource(FileInfo file)
            : base(file)
        {

            }
        }

                return file.Length;
