Correcting Length/Count mistyping
ReSharper prevents you from stumbling over mistyped
Length/Count properties of arrays/collections.
As soon as you erroneously start typing the
Count property for a usage of an array, ReSharper will allow you to pick it from the
completion list and replace with the
Length property, which you probably meant to type.
In a similar way, it will help you call the
Count property on a collection usage when you start typing the
Length property by mistake.
The correct property will be there as soon as you accept the completion suggestion:
void Foo(int[] array, List<int> collection)
{
if(array.Length == collection.Count
}Generating equality and flag checks for enumeration types
When you need to compare a value of enum type to one of the members of this enum, just type a dot and then pick the desired enum member in the completion list:
ReSharper will generate the comparison for you:
public enum Direction
{
North, East, South, West
}
void Turn(Direction whereTo)
{
if(whereTo == Direction.South
}Creating type parameter from usage in method parameters
When creating generic methods, you can easily add type parameters by typing
T for a new parameter and choosing the corresponding item in the completion list
ReSharper will add a new type parameter to the method declaration and bring you to a position where you can type the name of the type parameter in both its declaration and usage:
After you finish typing the name, press Enter or Tab to go on typing.
