==== Public Constructors ====
** {{wiki:PublicMethod.gif|}} ProjNetProjection() **

  * //This is the default constructor for this class.//
== Remarks ==
  * //This conctructor pass nothing. After this cconstructor , you should set the InternalProjectionParametersString property and ExternalProjectionParametersString property before open to use.//
== Parameters ==
<div newline></div>
** {{wiki:PublicMethod.gif|}} ProjNetProjection(String,String) **

  * //This is a constructor for the class.//
== Remarks ==
  * //This constructor allows you to pass in Proj4 text parameters for the to and from projection. The parameters typically look like "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs" You should use this constructor when you know the parameters. If you know the SRID directly you can use the other constructor that takes the SRID.//
== Parameters ==
  * //internalProjectionParametersString//
    * Type:String
    * Description:This parameter is the projection parameters describing the data.

  * //externalProjectionParametersString//
    * Type:String
    * Description:This parameter is the projection parameters describing the projection you want to go to.

** {{wiki:PublicMethod.gif|}} ProjNetProjection(Int32,Int32) **

  * //This is a constructor for the class.//
== Remarks ==
  * //This constructor allows you to pass in Proj4 srid parameters for the to and from projection. The parameters typically look like 4320 stands for "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs" and 4604 stands for " +proj=longlat +ellps=clrk80 +towgs84=174,359,365,0,0,0,0 +no_defs". You should use this constructor when you know the parameters. If you know the SRID directly you can use the other constructor that takes the SRID.//
== Parameters ==
  * //internalEpsgSrid//
    * Type:Int32
    * Description:This parameter is the projection srid parameter describing the data.

  * //externalEpsgSrid//
    * Type:Int32
    * Description:This parameter is the projection srid parameter describing the projection you want to go to.

==== Protected Constructors ====
==== Public Methods ====
** {{wiki:PublicMethod.gif|}} Dispose() **

  * //This is the dispose method for the class.//
== Remarks ==
  * //This dispose releases the handles of the Proj4 library. You should normally use Close instead of dispose unless you really want to never use this instance again. Normally when a layer is finished drawing it will call the Close of the projection class. This allows the object to be serialize but used again in the future. You should only use the Dispose method when you do not want to use this class again.//
