What is TextReader in C# ?

  • C# TextReader class is found in System.IO namespace.
  • It represents a reader that can be used to read text or sequential series of characters.
  • TextReader reads text characters from a file. It is internally used by many other types in the .NET Framework.
  • But you can access it for a general method of reading text content. It's usually better to use StreamReader in your programs.

Constructors:

Name Description
TextReader() Initializes a new instance of the TextReader class.

Methods:

Name Description
Close() Closes the TextReader and releases any system resources associated with the TextReader.
CreateObjRef(Type) Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.(Inherited from MarshalByRefObject.)
Dispose() Releases all resources used by the TextReader object.
Dispose(Boolean) Releases the unmanaged resources used by the TextReader and optionally releases the managed resources.
Equals(Object) Determines whether the specified object is equal to the current object.(Inherited from Object.)
Finalize() Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
GetHashCode() Serves as the default hash function. (Inherited from Object.)
GetLifetimeService() Retrieves the current lifetime service object that controls the lifetime policy for this instance.(Inherited from MarshalByRefObject.)
GetType() Gets the Type of the current instance.(Inherited from Object.)
InitializeLifetimeService() Obtains a lifetime service object to control the lifetime policy for this instance.(Inherited from MarshalByRefObject.)
MemberwiseClone() Creates a shallow copy of the current Object.(Inherited from Object.)
MemberwiseClone(Boolean) Creates a shallow copy of the current MarshalByRefObject object.(Inherited from MarshalByRefObject.)
Peek() Reads the next character without changing the state of the reader or the character source. Returns the next available character without actually reading it from the reader.
Read() Reads the next character from the text reader and advances the character position by one character.
Read(Char[], Int32, Int32) Reads a specified maximum number of characters from the current reader and writes the data to a buffer, beginning at the specified index.
ReadAsync(Char[], Int32, Int32) Reads a specified maximum number of characters from the current text reader asynchronously and writes the data to a buffer, beginning at the specified index.
ReadBlock(Char[], Int32, Int32) Reads a specified maximum number of characters from the current text reader and writes the data to a buffer, beginning at the specified index.
ReadBlockAsync(Char[], Int32, Int32) Reads a specified maximum number of characters from the current text reader asynchronously and writes the data to a buffer, beginning at the specified index.
ReadLine() Reads a line of characters from the text reader and returns the data as a string.
ReadLineAsync() Reads a line of characters asynchronously and returns the data as a string.
ReadToEnd() Reads all characters from the current position to the end of the text reader and returns them as one string.
ReadToEndAsync() Reads all characters from the current position to the end of the text reader asynchronously and returns them as one string.
Synchronized(TextReader) Creates a thread-safe wrapper around the specified TextReader.
ToString() Returns a string that represents the current object.(Inherited from Object.)

C# TextReader Example: Read All Data:

  • Let's see the simple example of TextReader class that reads data till the end of file.
using System;  
using System.IO;  
namespace TextReaderExample  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            using (TextReader tr = File.OpenText("e:\\f.txt"))  
            {  
                Console.WriteLine(tr.ReadToEnd());  
            }  
        }  
    }  
}

            using (TextReader tr = File.OpenText("e:\\f.txt"))  
            {  
                Console.WriteLine(tr.ReadLine());  
            }
