Type ? and press the Tab key to display the Code Snippet Picker. The question mark (?) character is also available in Visual Basic to assist with inserting snippets. Or, instead of using the Code Snippet Picker, access the short cut by typing “property” in the code window and then the pressing the Tab key. To accomplish the same task in Visual Basic, display the Code Snippet Picker and then select Common Code Patterns, choose Properties and Procedures and then choose the Define a Property context menu item. As soon as you change anything else in the code window, the replacement highlights are removed and the code must be edited the old fashioned way. Notice that the replacements remain highlighted, allowing you to tab through again and make further changes. When you have finished, the code appears like this. Press Tab again to move to the property name replacement and change it as well. The other references to that replacement within the snippet are then changed. Press the Tab key to move to the private member variable name replacement and change it. If you change the int to string, the data type of the property is also changed to string. In this example, the focus is initially moved to the data type of the private member. Tab between the replacements to change each one as needed. Edits cascade through the expansion, so when you change the replacement, all like-named replacements are changed to match. All like-named replacements are shown with a dotted rectangle. Focus is moved to the first highlighted replacement, shown in a highlighted rectangle. The highlighted portions of the snippet are called replacements. (You may need to press the Tab key twice if the auto list members drop down is open.) The following code is automatically inserted into the code window. Or, instead of using the Code Snippet Picker, use the short cut by typing “prop” in the code window and then press the Tab key. To accomplish this task in C#, display the Code Snippet Picker and then select the Visual C# > prop context menu item. But a more efficient way would be to use the property code snippet. You could type all of the code to create your private member variable (or backing variable) and then your property getter and setter. Say you want to add a property to a class. If you are in an XML code window, the Code Snippet Picker is as shown in Figure 3.įigure 1: Visual Basic provides a comprehensive set of task-based code snippets for your use.įigure 2: C# focuses on code snippets for common language constructs.įigure 3: XML code snippets provide easy access to XML syntax. Figure 2 shows the C# Code Snippet Picker. If you are using Visual Basic, the Code Snippet Picker will appear as in Figure 1. The snippets you have available depend on the language associated with the code window that has focus. The short cut associated with a snippet is displayed in the tool tip of the Code Snippet Picker entry. To insert a snippet using the short cut, type in the short cut and press the Tab key. Snippets also have short cuts to minimize the steps required to access a snippet. To cancel the Code Snippet Picker, press the Esc key. The Code Snippet Picker is then displayed for you to pick the desired snippet. To insert a snippet into a code window, place the cursor where the snippet is to be inserted, right-click to display the context menu, and select Insert Snippet or type CTRL + K, then X. Most code snippets are either common programming constructs, such as For loops, or common programming tasks, such as calling the ExecuteReader method of a SQLCommand. Inserting Code SnippetsĪ code snippet is a pre-built commonly used intelligent piece of code, sometimes referred to as an expansion template, which you can easily insert into a code window within the Visual Studio Integrated Development Environment (IDE). This article demonstrates how you can insert existing code snippets into your application, how to build your own snippets, and how to use the open-source Snippet Editor. Inserting snippets into your code is quick and easy AND saves you from all of that typing! For these types of code pieces, snippets are a perfect answer. Other pieces are more unique and cannot easily be made into standard methods, like Property procedures, For loops, or file input/output. Some of these pieces make sense as standard components or standard methods, like logging or validation. There are some pieces of code that you write over and over again. Using code snippets can make it quick to add common code pieces to your application.Ĭreating your own snippets allows you to create a library of custom code pieces and share them with other developers.
