以编程方式将用户权限添加到Sharepoint中的列表

如何以编程方式将用户权限添加到Sharepoint中的列表？我想将权限"Contribute"添加到某个列表的用户或组.我正在使用C#.

您可以使用SPRoleAssignment对象执行此操作,例如

// Assuming you already have SPWeb and SPList objects
...
SPRoleAssignment roleAssignment = new SPRoleAssignment("dom\\user", "user@dom", "user", "some notes");
SPRoleDefinition roleDefinition = web.RoleDefinitions.GetByType(SPRoleType.Contributor);
roleAssignment.RoleDefinitionBindings.Add(roleDefinition);
if (!myList.HasUniqueRoleAssignments)
{
    myList.BreakRoleInheritance(true); // Ensure we don't inherit permissions from parent
} 
myList.RoleAssignments.Add(roleAssignment);
myList.Update();
