In the previous article, we learned about Anonymous Type to define properties at runtime. But these properties are read only and the type will not allow changing it after creation. C# provides a class called DynamicExpando which will also allow adding the properties at runtime. But we can read and write the property values at runtime with this object. Since the type allow adding the members on the fly, the compiler will not perform any type checking. We can also…
JavaFx allows filling the closed shapes with a color. It is also possible to create an image and use it to fill the closed shapes. JavaFx provides the ImagePattern class which defines how the image pattern paints the target 2d shape. The ImagePattern class needs an Image object and fill rectangle (also called as Anchor Rectangle) definition. In this example, we will explore the ImagePattern class and fill the shapes rectangle and circle.
Null-Conditional Operator is available from C# 6.0 which makes more readable way of comparing the null object. The operator ‘?.’ is called Null-Conditional Operator. Some programmer calls this operator as Elvis Operator. In this example, we will see how to use this operator to check for the null objects.
In SQL Server, in some cases we need to replace a null value with more descriptive value. For example, while we select a record from a table, we can replace the null value from a column into a more meaningful value. The TSQL IsNull function can do the trick for us.
In C#, Anonymous Type can encapsulate the properties for more code readability. These types can store only properties with a restriction that they can be read only. Note, it also lives for a short-term say within the function scope. Let us see a C# Example here to explore it.
