XmlDocument.Load Method (String)

Loads the XML document from the specified URL.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public virtual void Load(
	string filename
)

Parameters

filename
Type: System.String
URL for the file containing the XML document to load. The URL can be either a local file or an HTTP URL (a Web address).

ExceptionCondition
XmlException

There is a load or parse error in the XML. In this case, a FileNotFoundException is raised.

ArgumentException

filename is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.

ArgumentNullException

filename is null.

PathTooLongException

The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.

DirectoryNotFoundException

The specified path is invalid (for example, it is on an unmapped drive).

IOException

An I/O error occurred while opening the file.

UnauthorizedAccessException

filename specified a file that is read-only.

-or-

This operation is not supported on the current platform.

-or-

filename specified a directory.

-or-

The caller does not have the required permission.

FileNotFoundException

The file specified in filename was not found.

NotSupportedException

filename is in an invalid format.

SecurityException

The caller does not have the required permission.

NoteNote

The Load method always preserves significant white space. The PreserveWhitespace property determines whether or not insignificant white space, that is white space in element content, is preserved. The default is false; white space in element content is not preserved.

If you want validation to occur, you can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see Validating XML Data with XmlReader.

This method is a Microsoft extension to the Document Object Model (DOM).
