Teach you to add permissions to the Process Control program

WF provides access control features, including two ways: Activedirectoryrole (through Active Directory Users) and webworkflowrole (asp.net role). Below I take the webworkflowrole way as the privilege control example to do the introduction, first needs to install the ASPNETDB database (by running Microsoft provided aspnet_regsql.exe file); The app.config files are configured as follows:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
　　 <addname="SqlServerConnection"
　　　　 connectionString="IntegratedSecurity=SSPI;server=localhost\SQLExpress;database=aspnetdb"/>
</connectionStrings>
<system.web>
　　 <roleManagerenabled="true"defaultProvider="SqlProvider">
　　　 <providers>
　　　　 <addname="SqlProvider" connectionStringName="SqlServerConnection" applicationName="ConsoleAppSample"
　　　　　 type="System.Web.Security.SqlRoleProvider,System.Web,Version=2.0.3600.0,Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a"/>
　　　 </providers>
　　 </roleManager>
</system.web>
</configuration>

The

generates roles through the following code:

 The following is a reference fragment: 
///<summary> 
///generation role 
///</summary> 
 private void Cre Ateroles () 
 {
 if (! System.Web.Security.Roles.RoleExists ("Personnel")) 
 {
 System.Web.Security.Roles.CreateRol E ("personnel"); 
 String[] users = {"Amanda", "Jones", "Simpson", "Peter"}; 
 String[] Personnelrole = {"Personnel"}; 
 System.Web.Security.Roles.AddUsersToRoles (Users, Personnelrole); 
} 
 if (! System.Web.Security.Roles.RoleExists ("Deptmanager")) 
 {
 System.Web.Security.Roles.CreateR OLE ("Deptmanager"); 
 String[] users1 = {"Betty", "Chris", "Anil", "Derek"}; 
 String[] Deptmanagerrole = {"Deptmanager"}; 
 System.Web.Security.Roles.AddUsersToRoles (users1, deptmanagerrole); 
} 
} 

If you use the login user "Betty" for the department manager role, through the following code can be the login user and the rights control combination: genericidentity genidentity = new GenericIdentity ("Betty"); Genidentity is passed into the process as a parameter of the event by invoking the external event activity.

Define public variables in the file (Workflow1.cs) of the process definition:

The following is a reference fragment:
Public workflowrolecollection eainitiators = new System.Workflow.Activities.WorkflowRoleCollection ();

Add the Department Manager role to the process role list through the following code:

The following is a reference fragment:
Load Department Manager role
Webworkflowrole eainitiatorsrole = new Webworkflowrole ("Deptmanager");
Eainitiators.add (Eainitiatorsrole);

WF implements process permission control by checking whether the incoming login parameter exists in a role in the process role list.
