The WorkflowCompilerParameters.


A string array that contains the paths to the files to compile. These files can be either code files (such as .vb or .cs) or workflow markup files. Workflow markup files must have an .xoml extension to be recognized by the compiler.

Return Value

The WorkflowCompilerResults representing the results of the operation.

Exception typeCondition

The following code example demonstrates how to use the Compile method. The code also creates new instances of the WorkflowCompiler and WorkflowCompilerParameters classes and sets some values. This code assumes that results is of type WorkflowCompilerResults. This code example is part of the Outlook Workflow Wizard SDK sample from the WizardForm.cs file. For more information, see Outlook Workflow Wizard.

// Compile the workflow
String[] assemblyNames = { "ReadEmailActivity.dll" };
WorkflowCompiler compiler = new WorkflowCompiler();
WorkflowCompilerParameters parameters = new WorkflowCompilerParameters(assemblyNames);
parameters.OutputAssembly = "CustomOutlookWorkflow" +  Guid.NewGuid().ToString()  + ".dll";
results = compiler.Compile(parameters, this.xamlFile);
