C# StringWriter Class
This class is used to write and deal with string data rather than files. It is derived class of TextWriter class. The string data written by StringWriter class is stored into StringBuilder.
The purpose of this class is to manipulate string and save result into the StringBuilder.

C# StringWriter Methods
|
Methods |
Description |
|
Close() |
It is used to close the current StringWriter and the underlying stream. |
|
Dispose() |
It is used to release all resources used by the TextWriter object. |
|
Equals(Object) |
It is used to determine whether the specified object is equal to the current object or not. |
|
Finalize() |
It allows an object to try to free resources and perform other cleanup operations. |
|
GetHashCode() |
It is used to serve as the default hash function. |
|
GetStringBuilder() |
It returns the underlying StringBuilder. |
|
ToString() |

|
WriteLineAsync(String) |
Writes a string followed by a line terminator asynchronously to the current string.(Overrides TextWriter.WriteLineAsync(String).) |
C# StringWriter Example
In the following program, we are using StringWriter class to write string information to the StringBuilder class. The StringReader class is used to read written information to the StringBuilder.
using System.IO;
using System.Text;
namespace CSharpProgram
{
class Program
{
static void Main(string[] args)
{
string text = "Hello, Welcome to the javatpoint \n" +
"It is nice site. \n" +
"It provides technical tutorials";
// Creating StringBuilder instance
StringBuilder sb = new StringBuilder();
// Passing StringBuilder instance into StringWriter
StringWriter writer = new StringWriter(sb);
// Writing data using StringWriter
writer.WriteLine(text);
writer.Flush();
// Closing writer connection
writer.Close();
// Creating StringReader instance and passing StringBuilder
StringReader reader = new StringReader(sb.ToString());
// Reading data
while (reader.Peek() > -1)
{
Console.WriteLine(reader.ReadLine());
}
}
}
}
Output:
It is nice site.
It provides technical tutorials
