Exemplos
The following code example creates a ForEachVariableMapping, sets the read-write properties, views the read-only properties, and sets up a mapping using the VariableName and ValueIndex properties.

public static void Main()
{
// Create the new application and package.
Application app = new Application();
Package package = new Package();
// Create ForEachLoop task
Executables executables = package.Executables;
ForEachLoop forEachLoop = executables.Add("STOCK:FOREACHLOOP") as ForEachLoop;
// Create a VariableMappings and VariableMapping objects.
ForEachVariableMappings forEachVariableMappings = forEachLoop.VariableMappings;
ForEachVariableMapping forEachVariableMapping = forEachVariableMappings.Add();
// Set the properties.
forEachVariableMapping.Description = "My ForEach Variable Mapping";
forEachVariableMapping.Name = "My Name is ForEachVariableMapping";
// View the read-only properties. CreationName can be blank.
Console.WriteLine("ID: {0}", forEachVariableMapping.ID);
Console.WriteLine("CreationName: {0}", forEachVariableMapping.CreationName);
// Create a mapping between the variable and its value.
forEachVariableMapping.VariableName = @"Id";
forEachVariableMapping.ValueIndex = 0;
// Add other tasks to ForEachLoop container.
//...
// Run the package when the rest of the code is finished.
