c# - String Join not working fine -
following code returns true, why? var inputs = new object[]{null, 1}; var output = string.join(",", inputs); console.writeline(output == "");//prints true > output = "" but following code working fine var inputs = new object[]{"", null, 1}; var output = string.join(",", inputs); console.writeline(output == "");//prints false > output = ",,1" is wrong in native implementation? from msdn : if first element of values null , join(string, object[]) method not concatenate elements in values instead returns string.empty . which special case overload using object[] . note isn't true other overloads, string[] one.
