Breakpoint

What is a Breakpoint in C#?

Definition and meaning of Breakpoint

A breakpoint, within the Context of C#, is an intentional stop marked within the Code of an Software where execution pauses for Debugging. This allows the Programmer to investigate the inner State of the utility at that factor.

A breakpoint helps to speed up the Debugging process in a big program by using allowing the execution to hold as much as a desired point earlier than debugging starts offevolved. This is Greater green than stepPing through the code on a line-by way of-line basis.

Conditions related to a breakpoint represent an Expression that determines whether or not the breakpoint is to be hit or skipped. When Filters that specify Procedure or Thread are attached to the breakpoint, it is less difficult to debug parallel Packages spread throughout multiple Processors.

What Does Breakpoint Mean?

Whenever a breakpoint is hit, the application and the Debugger are stated to be in "break" Mode, in the course of which the following moves may be finished:

• Inspect the values of nearby Variables set inside the cutting-edge Block of code in a separate neighborhood Window.
• Terminate the execution of a unmarried or more than one utility.
• Step through the code line by line. If there is no supply code underlying the execution statements, it ends in debugging in the diSASsembly window.
• Make Modifications to the program result by Viewing and modifying the values of variables.
• Move the execution factor with a purpose to resume the software execution from that point.
• CHange the code the usage of the “Edit and Continue” Function, and resume the execution with implemented modifications without having to forestall and restart the debugging consultation.

The key functions of breakpoints consist of:

• A breakpoint can be set and used even as Constructing an utility the use of debug statistics.
• A breakpoint may be set on the line of Source Code or on a function, with the capability to permit/ disable, edit and delete it.
• A breakpoint can also be set at a Memory Address inside the disassembly window and on a feature the use of the Call Stack window.
• Multiple breakpoints can be set on a line containing more than one Executable statements.
• A breakpoint can be set for all features with the same name (each overloaded strategies and capabilities going on in a couple of projects) in a unmarried step.
• Breakpoints are displayed inside the source code and disassembly window the use of crimson symbols called glyphs inside the left margin. The breakpoint tip displayed even as resting the Mouse on a glyph shows facts such as its related condition, hit count (used for tracking the Variety of times a breakpoint is hit), filter out, mistakes circumstance, etc.

The .NET Framework gives an choice to Insert a breakpoint programmatically through calling the SySTEM.Diagnostics.Debugger.Break Method, which reasons the utility to Interrupt when run below the debugger. However, it's far counseled that this be utilized in "Debug" mode only (by using using Compiler directive, #if DEBUG).

A breakpoint need to not be set on machine Components that shape part of a program with blended-mode, native and Managed Code because it may spoil the Common Language Runtime and purpose the debugger to stop responding. Also, breakpoints on strains of source code after line quantity 64,000 will no longer be hit.
