An indicator is a variable that contains the memory address of another variable memory. Which was used extensively in the elderly, procedural programming languages like C. Using pointers enables programmers to write very fast, low-level code. However, the leaders also are some security risks that are difficult to identify where the programs are written. Pointer use is permitted in C #, but there are restrictions that must be met. The project must be compiled with the “unsafe” command line argument. In addition, the pointer to appear in a section of code marked with the “unsafe” keyword. This section of the code runs in a “management” state, meaning that runs outside the control of the Common Language Runtime engine .

Create a console application

insecure project start the installation of Visual Studio (see Resources below). Select “New” then “Project” from the File menu in the main window. Expand the “C # Project Type” and highlight “Windows” in the “New Project” dialog box that appears .

Highlight “Console Application”, located in the “Visual Studio installed templates “in” Templates “panel. Click “OK.” This creates the .

Modify your project to allow the use of unsafe code. From the “Main Menu, select” Project “, then choose” (your project name) of properties. ” On the Construction of the tab “Properties” to open the dialog box, select the checkbox for “Allow unsafe code” in the “General”. This will add the “unsafe” command line argument to your project. Close the Properties dialog box .

Look for the “Home” in the “Program.cs” file and notification keys below it. Your code should be written between the keys for opening and closing. It’s OK to make a few blank lines for positioning the cursor after the first key and hit “Enter” several times .

Create a pointer

C # create a dangerous section of code in the newly space created by writing the “unsafe” keyword followed by the opening of a key ripple on the next line and curled a closing brace in line after that. Make some new, blank lines between the brackets by positioning the cursor after the first and pressing “Enter” a couple of times .

Create a pointer in C # in the “dangerous” on its agenda the kind of writing your pointer, an asterisk, and then a space, then the variable name pointer followed by a comma. For example, a pointer in C # called “myIntPointer” to an “int” data type looks like this: int myIntPointer *
