         float depth,
         int stencil
)

options
The surfaces to clear.
color
Color value to which the render target surface is cleared.
depth
New z value that this method stores in the depth buffer. This parameter can be in the range of 0.0 through 1.0 (for z-based or w-based depth buffers). A value of 0.0 represents the nearest distance to the viewer; a value of 1.0 represents the farthest distance.
stencil
Integer value to store in each stencil-buffer entry. This parameter can be in the range of 0 through 2n−1, where n is the bit depth of the stencil buffer.

Exception type	Condition
InvalidOperationException	No DepthStencilBuffer surface exists, or the active render target and depth stencil surface do not have the same pixel size and multisampling type. Unable to clear the depth or stencil buffer.
ObjectDisposedException	Clear was called after this GraphicsDevice was disposed.
