The indexer is a special attribute. The following is an example of the simplest indexer.
Is to find the value corresponding to the index number given the index number, similar to the attribute array
Public String This [String configname]{Get{Return System. configuration. configurationmanager. configurettings [configname];}
}
The indexer allows objects
At the end of the last time I left a few questions, because the power is not resolved, this one we continue the content of the previous article. Click here to go back to the previous article
Question 1:
Arrays have multidimensional, indexers can also be multidimensional???
Indexers can be multidimensional, and the indexer we define in the previous article is just a one-dimensional indexer, and as an array

An indexer is a name-value pair, you declare a class of name-value pairs, you can assign values to the specified elements of the array, or you can access the subscript for the specified element value (the individual thinks it's possible to write a similar list yourself, and there's no need to superfluous an extra method)?Complex indexer can be seen as a simple database, such as a person corresponding to the

OpenGL vertex array, opengl Vertex
In OpenGL, if you want to draw elements, the following operations are generally used:
glBegin(GL_LINES); glVertex3f(0.0f, 0.0f, 0.0f); glVertex3f(1.0f, 0.0f, 0.0f);glEnd();
However, if the number of vertices is too large, This method requires frequent function calls, which is too inefficient. This requires the use of vertex

The indexer is a special class member that allows an object to be accessed in an array-like manner.ProgramIt looks more intuitive and easier to write.

A matrix of N * m is given. Each lattice has a non-negative number, And a number must be selected to maximize the sum. The number in the lattice with adjacent edges cannot be selected at the same time.
First, I never thought about this network stream ...... Because the number of squares (1) is a State compression ......
I understood it after reading the question:
Due to the large data range, the status cannot be compressed. You need to use a network stream:

OpenGL uses the following formula to calculate the scattering light composition:
I is the intensity of reflected light, LD is the scattering component of the light source (gl_lightsource [0]. Diffuse), MD is the scattering coefficient of the material (gl_frontmaterial.diffuse ).This formula is the lambert diffuse reflection model. The cosine law of Lambert describes the brightness of the plane scattered light, which is proportional to the cosine of the plane normal and the angle of the clip of
An indexer allows an instance of a class or struct to be indexed in the same way as an array, with an indexer similar to an attribute, unlike an indexer whose access is a parameter.
