c# - WebAPI passed post parameters is null -


I'm testing with WebAPI 2 and I've created the following control method. 

  // Post API / value public string post ([CBD] string value) {string returnValue = "Return:" + value; Return return value; }

When I am posting the following message with Fiddler, the return method parameter returns. 

  POST http: // localhost: 50814 / api / value / http / 1.1 host: localhost: 50814 Content-Type: Application / Jason Content-Length: 14 {value: "new"}

I have already done my code as much as before but it still remains empty.

I think I am looking very simple but I am out of ideas Can someone help me?

If you use a simpler string than your controller's post method, only Try sending it to: 

  POST http: // localhost: 50814 / API / Value / HTTP / 1.1 Host: Localhost: 50814 Content-Type: Application / Jason Content-Length: 10 " MyStrin "

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
