Mutual conversion of the geometry type of the ArcGIS Server. Net Web ADF

The conversion between data types derives from the Web ADF support for multivariate data. Supporting multiple data sources means that Web applications can interact with different data sources in the same application. In general, each data source can work independently from the Web ADF, only to maintain its own specific APIs. However, because the web ADF binds them together, transformations between different data types are frequently encountered in development.
A variety of transformation classes are provided in the Web ADF, provided in a static way in different namespaces.

ESRI. ArcGIS.ADF.ArcGISServer.Converter: Provides a conversion from a COM object to a value object.
ESRI. ArcGIS.ADF.Converter:
ESRI. ArcGIS.ADF.Web.Converter:
ESRI. ArcGIS.ADF.Web.DataSources.ArcGISServer.Converter:

Because the function of GIS application and service is related to spatial data, it is mainly to deal with and analyze spatial data. For example, to get the point of the mouse click, or to obtain the elements of space, which in the process of implementing these functions, often and geometry deal with, and geometry will also be in the application of the various layers of conversion. This article focuses on the transformation of geometry types between the common APIs in the Web ADF and the various specific APIs.
1 There are several conversions, the three parties involved:
The geometry type of. NET,
The geometry type of the Web ADF: The geometry type of the web ADF here refers to the geometry type in the common API in the ADF.
The geometry type of the specific API.
For ArcGIS server, there are two types of objects in the corresponding specific API: one is the value objects in the ESRI.ArcGIS.ADF.ArcGISServer, and the other is the object in the Arcobjects.

There are detailed examples of conversions between the various types, and let's take a look at the following points:
