Yes. It is called Explicit Interface Implementation.

yes you can implement method by name of interface first

We have use the "Explicit Interface implementation" feature of C# to achieve this. For example // Declare the English units interface: interface IEnglishDimensions {float Length();float Width(); } // Declare the metric units interface: interface IMetricDimensions {float Length();float Width(); } //You can implement in the class like below class Box : IEnglishDimensions, IMetricDimensions {float lengthInches;float widthInches;public Box(float length, float width) {lengthInches = length;widthInches = width;} // Explicitly implement the members of IEnglishDimensions:float IEnglishDimensions.Length() {return lengthInches;}float IEnglishDimensions.Width() {return widthInches; } // Explicitly implement the members of IMetricDimensions:float IMetricDimensions.Length() {return lengthInches * 2.54f;}float IMetricDimensions.Width() {return widthInches * 2.54f;} }Warning : An interface member that is explicitly implemented cannot be accessed from a class instance: You have to cast it to interface type to call the method.Check this MSDN link for the full example :https://msdn.microsoft.com/en-us/library/aa288461(v=vs.71).aspx
