Methods

CreateNetworkTopologyStrategyReplicationProperty(Dictionary<String, Int32>)

Returns replication property for NetworkTopologyStrategy.

Declaration

Returns

Type	Description
System.Collections.Generic.Dictionary<System.String, System.String>	a dictionary of replication property sub-options.

CreateSimpleStrategyReplicationProperty(Int32)

Returns replication property for SimpleStrategy.

Declaration

public static Dictionary<string, string> CreateSimpleStrategyReplicationProperty(int replicationFactor)

Parameters
