We need to be cautious when we do this data population from another thread. Because, we can not use the controls directly in different threads. This has to […]
TreeView control in C# is used to display the items in hierarchical form. Each item in TreeView control is called a node. A node can have sub-nodes too; and each sub-node has it’s own nodes, and so on. All the nodes in the TreeView control are displayed in an hierarchical form, for better readability and […]
Usually, when we run the C# code, each statement executes synchronously; that means, one after another statement, executes sequentially. But, how do we instruct to run the code asynchronously? For example, watching a video while it is downloading; instead of waiting for the video to be completely downloaded. Of course, we call it streaming media; […]

String interpolation allows us to use the variables within the string, and variables will be replaced with the actual values at the time of execution. This gives better […]
Structures are composite types and can contain different types of elements. That means, structures can contain integer elements, strings, floating point elements, and even other structure types etc.,. Unlike in C language, C# structures can encapsulates both data elements and the functions which are operating on the data. Structures are value types. Defining a structure […]
Query Expressions contains a set of instructions to select the data source and retrieve the data from the selected data source. Define a Query C# provides clauses to define a query.

In our earlier Article, we have discussed about benefits and usage of virtual modifier in C#. We learnt that virtual keyword enables to override the members in the derived classes. In this Article, we will discuss about override and new modifiers. These modifiers are used during the inheritance in derived the class which will inherit […]
