SharePoint C# Get list of sites on which user has permission (Read, Contribute, Owner, Admin, Visitor)

Question

HI,
I wants to get list of sites on which user has permission, all permission name like (read, visitor, contribute, owner)
using (SPSite oSite = new SPSite(SPContext.Current.Site.Url))
foreach (SPWeb oWeb in oSite.RootWeb.GetSubwebsForCurrentUser())
permission = string.Empty;
foreach (SPGroup group in oWeb.Groups)
foreach (SPUser u in group.Users)
if (u.Name == (userName))
foreach (SPRole role in u.Roles)
permission += role.Name.ToString() + ", ";
} // Taking All Permission details of user
permission = " [" + permission.TrimEnd(", ".ToCharArray()) + "]";
my final string variable will have values like [Read, Visitor] or [Read] or [visitor, Read]
I wants to have all permission names and also geting error on u.Roles [Roles is absolute now],
 Help me to get permission by using SPRoleDefination etc
SPRoleDefinitionCollectionroleDefinitions
= oWeb.RoleDefinitions;
SPRoleDefinitionroleDefinition
foreach(SPRoleAssignmentroleAssigment
inoWeb.RoleAssignments)
 Thanks

Depending on how large your farm is and how many webapplications / site collections you need to enumerate to build this list, you might be better off using search to get the list of sites/webs that the user has access to (search results are security trimmed).
You could then enumerate just the list of sites returned to determine the exact permissions.
E.g. Code for getting a list of sites the user has access to:
var ssaProxy = (SearchServiceApplicationProxy)SearchServiceApplicationProxy.GetProxy(SPServiceContext.GetContext(SPContext.Current.Site));
var keywordQuery = new KeywordQuery(ssaProxy);
keywordQuery.RowLimit = 200;
keywordQuery.SelectProperties.Clear();
keywordQuery.SelectProperties.Add("Title");
keywordQuery.SelectProperties.Add("Url");
keywordQuery.ResultsProvider = SearchProvider.Default;
keywordQuery.QueryText = String.Format("contentclass:STS_Site OR contentclass:STS_Web");
keywordQuery.ResultTypes |= ResultType.RelevantResults;
ResultTableCollection searchResults;
searchResults = keywordQuery.Execute();
if (searchResults.Exists(ResultType.RelevantResults))
var searchResult = searchResults[ResultType.RelevantResults];
var results = new DataTable { TableName = "SearchResults" };
results.Load(searchResult, LoadOption.OverwriteChanges);
if (results.Rows.Count > 0)
var resultsText = new StringBuilder();
foreach (DataRow dataRow in results.Rows)
var urlToWeb = dataRow["Url"] as String;
//Perform your checking to determine the exact permissions
