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

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

I have seen many such comments on the Internet,AccessThe performance of Typed Dataset data is higher than that of untyped dataset. I have always been skeptical. After all, both are implemented based on DataSet. The former isCodeDetermine the structure when writing. The latter is determined at runtime. The efficiency of the two operations after instantiation is th

The dataset is ADO. The central concept of net. Datasets can be treated as an in-memory database, which is a separate collection of data that is not dependent on the database. (from Baidu Encyclopedia)Here's a code to sample the use of the dataset: (The following code is a button's Click event)1 using(SqlConnection conn =NewSqlConnection ("Data source=pc201507182002\\sqlexpress;initial catalog=123456;integr

It's common to know if a dataset is empty, but I'm starting to get a little vague on the concept of DS empty, and I looked at it online, and the results are as follows: The dataset is empty and there are no tables in the dataset.The dataset is empty, or a reference to a dataset type is null, meaning that the reference

A dataset, also known as a data set, data set, or data set, is a collection composed of data. A Data Set (or dataset) is a collection of data, usually in the form of tables.
