ResXResourceWriter Class

Writes resources in an XML resource (.resx) file or an output stream.

Namespace: System.Resources
Assembly: System.Windows.Forms (in

public class ResXResourceWriter : IResourceWriter, IDisposable
public class ResXResourceWriter implements IResourceWriter, IDisposable
public class ResXResourceWriter implements IResourceWriter, IDisposable

The ResXResourceWriter writes resources in XML format. To write a binary resource file, use ResourceWriter.

Resources are specified as name/value pairs using the AddResource method. Resource names are case-sensitive when used for lookups; but to more easily support authoring tools and help eliminate bugs, ResXResourceWriter does not allow a.resx file to have names that vary only by case.

To create a.resx file, create a ResXResourceWriter with a unique file name, call AddResource at least once, call Generate to write the resources file to disk, and then call Close to close the file. Calling Close will implicitly Generate the file if required.

The resources are not necessarily written in the same order they were added.

For more information on the format of a.resx file, see Resources in .Resx File Format.
