IndexBuffer Constructor (GraphicsDevice, Type, Int32, ResourceUsage, ResourceManagementMode)

Initializes a new instance of the IndexBuffer class.

Namespace: Microsoft.Xna.Framework.Graphics
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

public IndexBuffer (
         GraphicsDevice graphicsDevice,
         Type indexType,
         int elementCount,
         ResourceUsage usage,
         ResourceManagementMode resourceManagementMode
)

Parameters

• graphicsDevice
  The GraphicsDevice object to associate with the index buffer.
• indexType
  The type to use for index values.
• elementCount
  The number of values in the buffer.
• usage
  A set of options identifying the behaviors of this index buffer resource. It is good practice to match the usage parameter with the createOptions parameter in the GraphicsDevice constructor. If resourceManagementMode is ResourceManagementMode.Automatic, this value cannot be ResourceUsage.Dynamic.
• resourceManagementMode
  The memory management mode to use for this index buffer resource. If this value is ResourceManagementMode.Automatic, the runtime will recreate the resource when the graphics device is reset. If this value is ResourceManagementMode.Manual, this resource should be reinitialized when the graphics device is reset.

Exceptions
