how to split file name

You will need to create a new Class Library project in your BizTalk solution and add a single public static class that is marked as Serializable. Within that class, create single public static method called ExtractFilename (or any other name you feel is suitable) passing in the filename you received. The method should return a string.

Using either a string split, or substring methods extract the part of the filename you are looking for and return that from the method. You may also want to ‘ToUpper()’ the result before you return it from the method so your Decide shape only needs to check one case.

Add a reference to the project created above in your BizTalk project (that contains the orchestration that needs to consume this method) and in your orchestration Decide shape, reference the method in the left handside of your compaison, e.g.:

StaticClass.ExtractFilename(InputFilename) == “TELECOM”

If you need to put the value into a variable, simply assign it as follows and use the variable in your Decide shape comparison.

variable = StaticClass.ExtractFilename(InputFilename);

This approach is also testable using your favourite testing framework, in that the static ExtractFilename method can be tested in isolation from the orchestration expression. I use a similar approach, using RegEx’s to check that the method returns the expected string format.

Hope this helps, Nick.
