Not clear? What is "structure array"? It is array of structures instances? Why array? What's the goal of the application? "10 resolution"? What do you mean? 10 what? How this is related to the question?

The Array of slotInfo can be created as follows:

C#

slotInfo[] slotInfos = new slotInfo[10];
slotInfos[0] = new slotInfo() { HzRes = 1, VtRes=2, RR = 3, Bpp=4};
slotInfos[1]=new slotInfo() { HzRes = 5, VtRes=6, RR = 7, Bpp=8};

But, I think it is preferable to use generic List<T> as shown below,

XML

List<slotInfo> slotInfos2 = new List<slotInfo>();
slotInfos2.Add(new slotInfo() { HzRes = 1, VtRes=2, RR = 3, Bpp=4});
slotInfos2.Add(new slotInfo() { HzRes = 5, VtRes=6, RR = 7, Bpp=8});

since it accommodates the items without pre defining the size. So, the List can grow according to the requirement.

Whereas in case of the array if the number of elements exceed the size of the array declared, then a new array with new size has to be created and the old elements have to be transferred to the new array as explained here http://msdn.microsoft.com/en-us/library/bb348051(v=vs.90).aspx[^]

However, if an array is specifically required then it can be obtained from the List<T> using the ToArray method as shown below:

C#

var slotInfoArray = slotInfos2.ToArray();
