In C# 4.0 and later versions, you can omit arguments for any or all of the parameters if you want to use their default values. The Add method has four reference parameters, all of which are optional. Second, you can omit the ref keyword in the argument list. The compiler generates temporary variables to hold the argument values, and discards the variables when you return from the call. That is, you can send values directly, without creating a variable for each reference parameter.

First, you can send arguments to the reference parameters as if they were value parameters. These calls incorporate two other new features introduced in C# 4 that simplify calls to COM methods that have reference parameters.

CreateIconInWordDoc uses named and optional arguments to reduce the complexity of the method calls to xref.Documents.Add%2A and xref.Selection.PasteSpecial%2A. Paste method CreateIconInWordDoc, provided later in this step, into the Program class.

To illustrate additional ways in which C# 4, and later versions, enhances Office programming, the following code opens a Word application and creates an icon that links to the Excel worksheet. True is the default value for this property.Īdd the following line at the end of Main.Īn Excel worksheet appears that contains the data from the two accounts. The following lines show the casting.Ĭ# 4, and later versions, converts the returned Object to dynamic automatically if the assembly is referenced by the EmbedInteropTypes compiler option or, equivalently, if the Excel Embed Interop Types property is set to true. The foreach loop puts the information from the list of accounts into the first two columns of successive rows of the worksheet.Īdd the following code at the end of DisplayInExcel to adjust the column widths to fit the content.Įarlier versions of C# require explicit casting for these operations because ExcelApp.Columns returns an Object, and AutoFit is an Excel xref.Range method. The code inserts values into the first two columns of the first row of the worksheet.Īdd the following code at the end of DisplayInExcel. The equivalent statement in earlier versions of C# requires a placeholder argument: (Type.Missing).Īdd the following code at the end of DisplayInExcel. Because no argument is sent in the following code, Add uses the default template and creates a new workbook. Optional parameters, new in C# 4, enable you to omit the argument for that parameter if you want to use the parameter's default value. Method xref.Workbooks.Add%2A has an optional parameter for specifying a particular template. To declare a method that exports account information to ExcelĪdd the following method to the Program class to set up an Excel worksheet. Paste the following class definition into Program.cs, under the Program class.Īdd the following code to the Main method to create a bankAccounts list that contains two accounts.

In Solution Explorer, right-click the Program.cs file and then click View Code.Īdd the following using directives to the top of the code file:

See How to: Install Office Primary Interop Assemblies. If you do not see the assemblies, you may need to ensure they are installed and displayed. On the Assemblies page, select in the Component Name list, and then hold down the CTRL key and select. In Solution Explorer, right-click your project's name and then click Add Reference. The new project appears in Solution Explorer. Type a name for your project in the Name field. In the Templates pane, click Console Application. NET Framework 4 (or later version) is selected as a target framework. Look at the top of the New Project dialog box to make sure that. In the Installed Templates pane, expand Visual C#, and then click Windows. On the File menu, point to New, and then click Project. To complete this walkthrough, you must have Microsoft Office Excel 2007 and Microsoft Office Word 2007, or later versions, installed on your computer. You will then write code to add an Office Word document that contains an icon that is linked to the Excel worksheet. In this topic you will use the new features to write code that creates and displays a Microsoft Office Excel worksheet. The new features include named and optional arguments, a new type called dynamic, and the ability to pass arguments to reference parameters in COM methods as if they were value parameters.
