用这种方法可以调用所有Toolbox中工具，只要具备许可。总体感觉没有python方便。
In VB, you execute any tool through the Execute method of the GeoProcessor object. In
order to access any method or property of the GeoProccessor object you first need to
declare an IGeoProccessor variable and set it to GeoProccessor object. You set the
parameters of a tool through a variant array. Populate the variant array with each
parameter in the same sequence as the usage of tool would show. You must ensure all the
properties marked as required are set; you may also wish to set properties marked as
Optional. See the example below showing how to access the Erase tool and set its
parameters:
'//Initialize the Geoprocessor
Dim GP As IGeoProcessor
Set GP = New GeoProcessor
'//Declare 3 variables for input and output parameters
Dim in_features As String
Dim erase_features As String
Dim out_features As String
'//Define the input/output parameter variables
in_features = "C:\data\erase\Input.shp"
erase_features = "C:\data\erase\Erase.shp"
out_features = "C:\data\erase\Output.shp"
'//Declare and set a variant array to hold the parameters
Dim parameters As IVariantArray
Set parameters = New VarArray
'//Populate the variant array with the parameters
parameters.Add (in_features)
parameters.Add (erase_features)
parameters.Add (out_features)
'//Now execute the Erase tool
GP.Execute "Erase", parameters, Nothing

中文可参考《学习在 ArcEngine 中使用 Geoprocessing》，写得比较仔细。
