The difference between the count () and length of a C # array

The Length in the C # array represents the number of array items and is a property .

Count () also represents the number of items, and is a method whose value is the same as Length. But actually strictly speaking Count () is not the contents of the array, but rather the content of IEnumerable. This is why C # 2.0 is not available with count (), and 3.0 can be used after the reason of Count ().

For arrays, it is said that the Length is faster than Count ().

So the general case: array I use length,ienumerable (like List) I use Count ().
