Call a class in an orchestration

[quote:431c7f32c0]I have a shape in an orchestration, and I wan%u00b4t to call to a class that inserts rows in a database , and I wan%u00b4t to pass a parameter extract of the xml on the shape…
How Can I do that? [/quote:431c7f32c0]

If the method is not static, create a variable and set it’s type to .NET and choose the class. Then in an expression shape, you can say:
[code:1:431c7f32c0] myvar = new MyNamespace.MyClass(whatever);
myvar.MyMethod(a,b,c); [/code:1:431c7f32c0]

If you have a static method, you can just call it directly without the variable.

I’m not sure what you mean \”pass a parameter extract of the xml on the shape\”. You can use xpath to pull of a selection of nodes from a message, and you can pass a message to a C# method as a System.Xml.XmlDocument.
