If you do not use a full diagram, you can constructk-NNGraph (that is, a point is only itskThe nearest neighbor has a side), but this may cause the resulting graph to be not connected, to be processed to make it connected. 2.

Are you talking about typed dataset and untyped dataset?
Typed Dataset is derived from dataset. It generates a dataset Based on the predefined data schema and imposes a strong type constraint on fields in the dataset. You can see

Today, a storage task was previously executed with multiple select statements in dataset and then stored in dataset. However, in c # moblie development, multiple Select statements cannot be executed simultaneously. Only one select table is saved to dataset once.If DataSet. table. add (tablename); is used, we can only u
Take the table name "MyTable" and the field FirstName varchar (30) and FamilyName varchar (30) as an example.
Non-strong (UnTyped) Dataset does not need to define the attributes of each field of the corresponding table in advance, you can directly obtain the values from the queried result set (non-strong (UnTyped) Dataset), for example:String lFirstName =LDs. Table ["MyTable"]. Rows [0] ["FirstName"]. ToStr
