C# StringReader

Introduction

StringReader is a class in C# that reads a string as text line by line. It inherits from the TextReader class and provides a read-only stream of text characters from a specified string. The StringReader class is useful when you have a string with some formatted text, and you want to parse or read it line by line.

Syntax

public sealed class StringReader : TextReader

Constructors

The StringReader class has only one constructor that takes a string as a parameter.

public StringReader(string s)

Properties

The StringReader class has the following properties:

| Property | Description | | ----------------- | ------------------------------------------------------------ | | BaseStream | Gets the underlying stream from which the StringReader object reads. | | CurrentEncoding | Gets the Encoding used by the current instance of the StringReader class. |

Methods

The StringReader class provides the following methods:

| Method | Description | | ---------------- | ------------------------------------------------------------ | | Close | Closes the StringReader object. | | Dispose | Releases all resources used by the current instance of the StringReader class. | | Peek | Returns the next available character without reading it from the current source. | | Read | Reads the next character from the input string and advances the character position by one character. | | ReadBlock | Reads a specified maximum number of characters from the current string and writes the data to a buffer, beginning at the specified index. | | ReadLine | Reads a line of characters from the input string and returns the data as a string. | | ReadToEnd | Reads all characters from the current position to the end of the input string and returns them as one string. |

            string line;
            while ((line = reader.ReadLine()) != null)
            {

            }
        }
    }
}
