Question

I need to create a POST method in WebApi so I can send data from application to WebApi method. I\'m not able to get header value.

Here I have added header values in

Answer 1

try these line of codes working in my case:

IEnumerable<string> values = new List<string>();
this.Request.Headers.TryGetValues("Authorization", out values);

Answer 2

In case someone is using ASP.NET Core for model binding,

https://docs.microsoft.com/en-us/aspnet/core/mvc/models/model-binding

There's is built in support for retrieving values from the header using the [FromHeader] attribute

public string Test([FromHeader]string Host, [FromHeader]string Content-Type )
{
     return $"Host: {Host} Content-Type: {Content-Type}";
}

Answer 3

As someone already pointed out how to do this with .Net Core, if your header contains a "-" or some other character .Net disallows, you can do something like:

public string Test([FromHeader]string host, [FromHeader(Name = "Content-Type")] string contentType)
{
}

You need to get the HttpRequestMessage from the current OperationContext. Using OperationContext you can do it like so

OperationContext context = OperationContext.Current;
MessageProperties messageProperties = context.IncomingMessageProperties;

HttpRequestMessageProperty requestProperty = messageProperties[HttpRequestMessageProperty.Name] as HttpRequestMessageProperty;

string customHeaderValue = requestProperty.Headers["Custom"];
