How to add watermark to PDF file in C# , VB.NET | WinForms - PDF
3 Aug 2018 ... For example, you can apply a “Confidential” text to the pages with sensitive information. Syncfusion Essential PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can add watermark to PDF file in C# and VB.

All the .NET languages are compiled into another lower-level language before the code is executed. This lower-level language is the MSIL (Microsoft Intermediate Language), or just IL. The CLR, the engine of .NET, uses only IL code. Because all .NET languages are designed based on IL, they all have profound similarities. This is the reason that the VB and C# languages provide essentially the same features and performance. In fact, the languages are so compatible that a web page written with C# can use a VB component in the same way it uses a C# component, and vice versa. The .NET Framework formalizes this compatibility with something called the CLS (Common Language Specification). Essentially, the CLS is a contract that, if respected, guarantees that a component written in one .NET language can be used in all the others. One part of the CLS is the CTS (common type system), which defines data types such as strings, numbers, and arrays that are shared in all .NET languages. The CLS also defines object-oriented ingredients

such as classes, methods, events, and quite a bit more. For the most part, .NET developers don t need to think about how the CLS works, even though they rely on it every day. Figure 1-5 shows how the .NET languages are compiled to IL. Every EXE or DLL file that you build with a .NET language contains IL code. This is the file you deploy to other computers.

< xml version="1.0" encoding="utf-8" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent"

The CLR runs only IL code, which means it has no idea which .NET language you originally used. Notice, however, that the CLR actually performs another compilation step it takes the IL code and transforms it to native machine language code that s appropriate for the current platform. This step occurs when the application is launched, just before the code is actually executed. In an ASP.NET application, these machine-specific files are cached while the web application is running so they can be reused, ensuring optimum performance.

Note You might wonder why .NET compilers don t compile straight to machine code. The reason is that

The Order domain class includes attributes that really don t seem like they belong in an Order class (see Figure 2-14). The most likely cause is that the modeler has mapped these domain classes directly from a relational database schema. Figure 2-15 gives the corrected diagram. The extra attributes have been separated out into their own domain classes (Customer Account and Dispatch). Note that we d generally not show the attributes at all during domain modeling.
