: System.Security.SecurityException



Fiz um aplicativo que está hospedado na Locaweb.

Preciso ler uma planilha Excel e importar os dados para o sistema.

Porém, sempre que clico no botão para executar a operação, dá um erro de segurança.

O que devo fazer para consegui importar os dados da planilha excel?

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ZoneIdentityPermission, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
