|---|---|
| Close () | It is used to close the current StringWriter and the underlying stream. |

| Finalize () | It allows an object to try to free resources and perform other cleanup operations. |
| Get Hash Code () | It is used to serve as the default hash function. |
| Get String Builder () | It returns the underlying StringBuilder. |

string text = "Hello, Welcome to the Wikitechy \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());
