TFS: To make merge from stablility or build Label to trunk

For example, you have code labelled "Stable_1" in development branch and you need to merge the code to trunk.

string SourceLabel = "Stable_1"

GetStatus status = workspace.Merge

    (DevelopmentPath, TrunkPath,

    null, VersionSpec.ParseSingleSpec( "L" + SourceLabel, null ),

    LockLevel.CheckOut, RecursionType.Full, MergeOptions.None);
