How to overwrite a xml file in c#

DisplayFileStatus fileInfo ; Console.

The CreateText method returns an object of type StreamWriter, which is then used to write a text string to the newly created file, after which the open file handle is released by invoking StreamWriter. Furthermore the code snippet illustrates instantiating an object of type FileInfowhich is specified to reference the previously newly created file.

Setting a file to read only — Method 1 Console. WriteLine "Attempting to set read only: WriteLine ; This method simply sets the property FileInfo.

Setting a file to read only — Method 2 Console. Setting a file to read only — Method 3 Console. Attributes property, which is an enumeration of type System. The FileAttributes enumeration as part of its declaration implements [FlagsAttribute].

When regarding the FileInfo. Attributes property as a bit field it logically follows that bitwise operations can be performed. The code snippet performs a bitwise OR operation specifying the enumeration value FileAttributes.

The FileInfo class does not have static methods and can only be used on instantiated objects. The FileInfo object represents a file on a disk or network location. It also provides instance methods for the creation, copying, deletion, moving, and opening of files, and aids in the creation of FileStream objects.

Attributes, which is an enumeration property of type System. FileAttributesbut also a bit field as discussed earlier. Reversing the bit values of FileAttributes. ReadOnly then applying the resulting values as an operand to a bitwise AND operation results in removing FileAttributes.

ReadOnly as a flag set on the FileInfo. Complete Sample Code The code listing below represents the entire code sample. You can also download the complete Visual Studio project source code here.'
