Accessing request headers

[Umashankar Sharma]

I am actually a newbie in C#, but can you let me know how to access the request headers in my handler. I am using the below in my config file. Wanted to know how to access this in handler.

.DefaultHttpHeaderBindingConfiguration(new HeaderBindingConfiguration
{
PropertyFromHeaderMappings = new Dictionary<string, string>
{
{ "OperationId", "x-operation-id" }
