Generate code from usage
ReSharper lets you use code symbols ( classes, methods, variables, properties, fields, and so on) before you declare them. When ReSharper detects an undeclared symbol, it suggests one or more quick-fixes Alt+Enter for generating a declaration based on the usage, and then smartly adjust the declaration according to the usage context:
For example, if you create a method from usage, ReSharper will not only create a method, but also detect its return type and types of its parameters:
For additional examples of how ReSharper creates code symbols from usages, see Undefined variable and Undefined method call samples in the Examples of quick-fixes.
