Question : c# make parameter optional
Answered by : alex-yousef
{"tags":[{"tag":"p","content":"C#, you can make a parameter optional by specifying a default value for that parameter in the method signature. "},{"tag":"textarea","content":"public void MyMethod(string requiredParam, int optionalParam = 0)\n{\n // method body\n}\n","code_language":"csharp"},{"tag":"p","content":"the optionalParam parameter has a default value of 0, so it's optional. If you call MyMethod without providing a value for optionalParam, it will default to 0. If you provide a value for optionalParam, it will use the provided value instead of the default value. The requiredParam parameter does not have a default value, so it must always be provided when calling MyMethod. "}]}Source : | Last Update : Sat, 11 Mar 23
