# Example applications for .NET

The `/samples/cs` directory contains somer sample applications written in C#, designed to illustrate use of the Saxon API available in the `Saxon.Api` namespace. In particular there are three programs `ExamplesHE.cs`, `ExamplesPE.cs`, and `ExamplesEE.cs` relevant to Saxon-HE, Saxon-PE, and Saxon-EE respectively; each shows various ways of invoking XSLT, XQuery, XPath, and schema validation where appropriate. The idea is that you should be able to cut and paste a suitable fragment of code into your own application as a quick way of getting started.

The main value of these samples is in reading the source code rather than in actually running them; however, running them is also a good check that your installation has been set up correctly. a quick look at the comments in the source should enable you to see how they are executed. Note that they all require the environment variable `SAXON_HOME` to be set to the directory where Saxon is installed: this is used to find the sample data files.

The example applications can be run from the command line. They take the following arguments:

- -dir:samples - provides the name of the samples directory from the saxon-resources download. The default uses the SAXON_HOME environment variable - but it's normally best to supply this parameter explicitly.

- -ask:yes|no - with ask:yes (the default), the application prompts after each test to ask if you want to continue.

- -test:testname - supplies the name of the test you want to run, or "all" (the default) to indicate all tests.

Also in the same directory is an application `TestRunnerProgram.cs` which is a test harness for running the XSLT, XQuery, and XSD test suites published by W3C (in the case of XSLT, the test data is available to W3C members only).
