Remarks

A SecurityException exception is thrown when a caller does not have the permissions required to access a resource. The following example instantiates a PermissionSet object that includes a UIPermission object to allow access to UI objects and the Clipboard and a RegistryPermission object to prevent registry access. The call to the PermissionSet.PermitOnly method means that these permissions will apply regardless of the permissions assigned to the caller. As a result, the attempt to create a registry key throws a SecurityException.

public class Example
{
   public static void Main()
   {
      PermissionSet perms = new PermissionSet(null);
      perms.AddPermission(new UIPermission(PermissionState.Unrestricted));
      perms.AddPermission(new RegistryPermission(PermissionState.None));
      perms.PermitOnly();
      
      try {
          RegistryKey key = Registry.CurrentUser.CreateSubKey("MyCompany\\Applications");
          Console.WriteLine("Registry key: {0}", key.Name);
      }
      catch (SecurityException e) {
         Console.WriteLine("Security Exception:\n\n{0}", e.Message);      
      }
   }
}
// The example displays the following output:
//    Security Exception:
//    
//    Request for the permission of type 'System.Security.Permissions.RegistryPermission, 
//    mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Constructors

SecurityException()	Initializes a new instance of the SecurityException class with default properties.
SecurityException(SerializationInfo, StreamingContext)	Obsolete. Initializes a new instance of the SecurityException class with serialized data.
SecurityException(String, Exception)	Initializes a new instance of the SecurityException class with a specified error message and a reference to the inner exception that is the cause of this exception.
SecurityException(String, Type, String)	Initializes a new instance of the SecurityException class with a specified error message, the permission type that caused the exception to be thrown, and the permission state.
SecurityException(String, Type)	Initializes a new instance of the SecurityException class with a specified error message and the permission type that caused the exception to be thrown.
SecurityException(String)	Initializes a new instance of the SecurityException class with a specified error message.

InnerException	Gets the Exception instance that caused the current exception. (Inherited from Exception)
Message	Gets a message that describes the current exception. (Inherited from Exception)
Method	Gets or sets the information about the method associated with the exception.
PermissionState	Gets or sets the state of the permission that threw the exception.

PermitOnlySetInstance	Gets or sets the permission, permission set, or permission set collection that is part of the permit-only stack frame that caused a security check to fail.
RefusedSet	Gets or sets the refused permission set of the assembly that caused the SecurityException.
Source	Gets or sets the name of the application or the object that causes the error. (Inherited from Exception)

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetBaseException()	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetObjectData(SerializationInfo, StreamingContext)	Obsolete. Sets the SerializationInfo with information about the SecurityException.
GetType()	Gets the runtime type of the current instance. (Inherited from Exception)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a representation of the current SecurityException.

Events
