Parameters

state

A PermissionState value.

The value of the state parameter is either PermissionState.None or PermissionState.Unrestricted, respectively yielding fully restricted or fully unrestricted access to all security variables. If you specify PermissionState.None, then you can give access to individual URIs using AddPermission.

The following example creates an instance of WebPermission and gives access rights to specific URLs.

// Create a WebPermission instance.  
WebPermission myWebPermission1 = new WebPermission(PermissionState.None);

// Allow access to the first set of URL's.
myWebPermission1.AddPermission(NetworkAccess.Connect,"http://www.microsoft.com/default.htm");
myWebPermission1.AddPermission(NetworkAccess.Connect,"http://www.msn.com");

// Check whether all callers higher in the call stack have been granted the permissionor not.
myWebPermission1.Demand();


// Create a WebPermission instance.  
WebPermission myWebPermission1 = new WebPermission(PermissionState.None);
// Allow access to the first set of URL's.
myWebPermission1.AddPermission(NetworkAccess.Connect,
    "http://www.microsoft.com/default.htm");
myWebPermission1.AddPermission(NetworkAccess.Connect,
    "http://www.msn.com");
// Check whether all callers higher in the call stack have been granted
// the permissionor not.
myWebPermission1.Demand();
