How to safely check if a dynamic object has a field or not

c#

Solution

You need to surround your dynamic variable with a try catch, nothing else is the better way in makking it safe.

try
{
    dynamic testData = ReturnDynamic();
    var name = testData.Name;
    // do more stuff
}
catch (RuntimeBinderException)
{
    //  MyProperty doesn't exist
}

Problem

I'm looping through a property on a dynamic object looking for a field, except I can't figure out how to safely evaluate if it exists or not without throwing an exception. ``` foreach (dynamic item in routes_list["mychoices"]) { // these fields may or may not exist int strProductId = item["selectedProductId"]; string strProductId = item["selectedProductCode"]; } ```
