- Hi I have a large text file that i want to read into java and parse the information in it. Can anyone tell me the best way about doing this. Example of one line of the file (each line is the same. Reading in a text file and parsing it in java.
- Here i explained with an example, how to implement error logging and exception handling in ASP.Net using C#. The errors and exceptions will be written to a Text file.
How to: Read Text from a File.; 2 minutes to read Contributors. All; In this article. The following examples show how to read text synchronously and asynchronously from a text file using.NET for desktop apps. In both examples, when you create the instance of the StreamReader class, you provide the relative or absolute path to the file. The following examples assume that the file named TestFile.txt is in the same folder as the application. ASP.NET File Uploading - Free ASP.NET Tutorials, Reference Manual, and Quick Guide for Beginners. ASP.NET has two controls that allow users to upload files to the web server. Once the server receives the posted file data, the application can save it, check it, or ignore it. Providing a browse button and a text box for entering the filename.
-->The following examples show how to read text synchronously and asynchronously from a text file using .NET for desktop apps. In both examples, when you create the instance of the StreamReader class, you provide the relative or absolute path to the file.
Note
These code examples do not apply to developing for Universal Windows (UWP) apps, because the Windows Runtime provides different stream types for reading and writing to files. For an example that shows how to read text from a file in a UWP app, see Quickstart: Reading and writing files. For examples that show how to convert between .NET Framework streams and Windows Runtime streams, see How to: Convert between .NET Framework streams and Windows Runtime streams.
Example: Synchronous read in a console app
The following example shows a synchronous read operation within a console app. This example opens the text file using a stream reader, copies the contents to a string, and outputs the string to the console.
Important
The example assumes that a file named TestFile.txt already exists in the same folder as the app.
Example: Asynchronous read in a WPF app
The following example shows an asynchronous read operation in a Windows Presentation Foundation (WPF) app.
