Private void button2_Click(object sender, System.EventArgs e) StreamReader reader = new StreamReader(winDir "\\system.ini") try.catch is to deal with a 0 byte file. Private void button1_Click(object sender, System.EventArgs e) Paste the following code in the Code-Behind Editor window. Open the code window for Form1 ( Form1.cs). In Visual C#, create a new Windows Forms Application. It is important to consider these possibilities when you write code and to handle the exceptions that may be generated. The files may not exist, the files may be in use, or users may not have rights on the files or folders that they are trying to access. Many things can go wrong when a user gains access to files. string files= Directory.GetFiles(winDir) This sample code uses the GetFiles method of the Directory class to get a listing of files. string dirs = Directory.GetDirectories(winDir) This sample code uses the GetDirectories method of the Directory class to get a list of folders. string drives = Directory.GetLogicalDrives() For this sample, the results appear in a ListBox control. This sample code uses the Directory and Drive classes to list the logical drives on a system. FileInfo FileProps =new FileInfo(winDir "ĪddListItem("File Name = " FileProps.FullName) ĪddListItem("Creation Time = " FileProps.CreationTime) ĪddListItem("Last Access Time = " FileProps.LastAccessTime) ĪddListItem("Last Write TIme = " FileProps.LastWriteTime) ĪddListItem("Size = " FileProps.Length) The properties appear in a ListBox control. This sample code uses a FileInfo object to access a file's properties. Writer.WriteLine("File created using StreamWriter class.") ĪddListItem("File Written to C:\\KBTest.txt") ![]() If you have an existing file, you can open it in the same way. This sample code uses a StreamWriter class to create and write to a file. StreamReader reader=new StreamReader(winDir "\\system.ini") There are many ways to determine when the end of the file is reached this sample uses the Peek method to examine the next line before reading it. The try.catch block is used to alert the program if the file is empty. The contents of the file are added to a ListBox control. The following sample code uses a StreamReader class to read the System.ini file. Instead of declaring and using the addListItem function, you can use the following statement directly: (value) The addListItem function is declared as follows: private void addListItem(string value) Include the System.IO namespace, as follows: using System.IO ĭeclare the winDir variable as follows: string winDir=("windir") If you want to use the following code samples directly, be aware of the following: The Step-by-step example section describes how to create a sample program that demonstrates the following file I/O operations: The examples in this article describe basic file I/O operations. NET Framework, offer functionality that is not available with the FSO, without the overhead of the Interop layer. ![]() However, the File, FileInfo, Directory, DirectoryInfo classes, and other related classes in the. NET generates a wrapper for the component for you if you want to use it. NET requires that access to the object be through the Interop layer. Because the FileSystemObject is a Component Object Model (COM) component. You can still use the FileSystemObject in. To make the transition easier, the functionality that is demonstrated in How To Use FileSystemObject with Visual Basic. NET is similar to the FileSystemObject (FSO) that is popular with many Visual Studio 6.0 developers. NET Framework, you will find that the object model for file operations in. This step-by-step article shows you how to do six basic file input/output (I/O) operations in Visual C#. NET Framework Class Library namespaces System.IO and System.Collections. How to do basic file I/O in Visual C or in Visual C . How to do basic file I/O in Visual Basic 2005 or in Visual Basic. It is one of the best code editors which runs only in Windows environment, and it uses a GPL license. It uses pure win32 API which provides more execution speed and smaller program size. 1) Notepad Notepad is a popular free-to-use code editor written in C . Although pre-.NET Visual Basic is no longer supported or updated by Microsoft, the VBA programming language was upgraded with the introduction of Visual Basic for Applications 7 in Microsoft Office applications in 2010. Visual Basic for Applications (VBA) is an implementation of Microsoft’s event-driven programming language Visual Basic 6, which was declared legacy in 2008, and is an associated integrated development environment (IDE). ![]()
