check share point group exists or not

Hi All,

I am new to this sharepoint.

My question is to activate feature using visual c# in which it has to check whether the share point group exists or not and if it doesn't exists then create a share point group in a site and add users to that group and give full control permissions for those users.This feature should be accessed to only one site collection.

Hi Kamala,

Step 1 :Create sharepoint project using Visual studio using below article,

Step 2: Then add the feature in the project and then add the event receiver for the feature

Step 3: in side the feature receiver add the below code to check whether the group is exist or not

SPWeb root = site.RootWeb;
SPGroup group = null; // Check if the group exists
try
{
group = root.SiteGroups["The Group Name"];
}
catch { } // If it doesn't, add it
if (group == null)
{
root.SiteGroups.Add("The Group Name", member, root.Author, "Your Group Description");
group = root.SiteGroups["The Group Name"]; // Add the group's permissions
SPRoleDefinition roleDefinition = root.RoleDefinitions.GetByType(SPRoleType.Contributor);
SPRoleAssignment roleAssignment = new SPRoleAssignment(group);
roleAssignment.RoleDefinitionBindings.Add(roleDefinition);
root.RoleAssignments.Add(roleAssignment); root.Update();
}

Step 4 Here is the code to add the users in SP group

using (SPWeb oWebsite = SPContext.Current.Site.AllWebs["Web_Site_Name"])
{
SPGroup oGroup = oWebsite.SiteGroups["Group_Name"];
SPUserCollection collUsers = oWebsite.Users;
foreach (SPUser oUser in collUsers)
{
oGroup.AddUser(oUser);
}
}
