[amp_mcq option1=”CreateText method” option2=”AppendText method” option3=”OpenText method” option4=”WriteText method” correct=”option2″]<\/p>\n
The correct answer is B. AppendText method.<\/p>\n
The AppendText method is used to open a sequential file for append. This means that new data can be added to the end of the file, but existing data cannot be changed or deleted. The AppendText method is useful for creating log files or for adding new data to a database.<\/p>\n
The CreateText method is used to create a new text file. The OpenText method is used to open an existing text file. The WriteText method is used to write data to a text file.<\/p>\n
Here is an example of how to use the AppendText method:<\/p>\n
“`
\nusing System.IO;<\/p>\n
public class Program
\n{
\n public static void Main(string[] args)
\n {
\n \/\/ Create a new StreamWriter object for the file “myFile.txt”.
\n StreamWriter writer = new StreamWriter(“myFile.txt”, true);<\/p>\n
\/\/ Write some data to the file.\n writer.WriteLine(\"This is some data.\");\n\n \/\/ Close the StreamWriter object.\n writer.Close();\n}\n<\/code><\/pre>\n}
\n“`<\/p>\n
This code will create a new file called “myFile.txt” and write the text “This is some data.” to the file.<\/p>\n","protected":false},"excerpt":{"rendered":"
