wwDotNetBridge::CreateArray

Creates a new ComArray instance that you can manipulte easily from FoxPro.

ComArray is a special wwDotnetBridge wrapper for .NET arrays that facilitates accessing .NET arrays without marshalling them into FoxPro and losing their .NET object status and so their updateability. ComArray is the preferred mechanism to manipulate .NET arrays from FoxPro as it allows the .NET array to stay in .NET and only marshals individual array items into FoxPro.

ComArray instances can be created with:

  • loBridge.CreateArray(<.NET typename>)
  • loBridge.GetProperty(loInst,"ArrayProperty")
  • loBridge.InvokeMethod(loInst,"someMethod") where it returns an Array

ComArray is a wrapper type that can be passed to InvokeMethod() or SetProperty() and is converted by wwDotNetBridge into the native array type that is stored in the Value property thus allow keeping the array entirely in .NET without having to be marshaled into FoxPro arrays.

o.CreateArray(lcBaseTypeName)

Parameters

lcDotnetElementType
The full .NET typename for the array elements to be created. Each element of the array will be of this type.

Use System.Object if you need to pass mixed types for each element rather than a single type for each element.

Example

loBridge = CREATEOBJECT("wwDotNetBridge")

loService = CREATEOBJECT("Sample.MyService")

*** Create an instance of the array with the 
*** specific type of the elements
LOCAL loArr as Westwind.WebConnection.ComArray
loArr = loBridge.CreateArray("System.Object")

*** Add Items
loArr.AddItem("New Item")
loArr.AddItem(10)

*** Create a .NET object and set properties
loCust = loBridge.CreateInstance("Sample.Customer")
loCust.Company = "West Wind"
loCust.Entered = DateTime()

*** Add the object to the array
loArr.AddItem(loCust)

*** Now call a method that takes the array as a parameter
loBridge.InvokeMethod(loService,"PassArray",loArr)
