从代码隐藏中调用ASP.NET Web API

Question

如何直接从代码隐藏调用ASP.NET Web API？或者我应该调用从代码隐藏调用getJSON方法的javascript函数？

我通常有类似的东西:

    function createFile() {
        $.getJSON("api/file/createfile",
        function (data) { 
            $("#Result").append('Success!');
        });
    }

任何指针赞赏.TIA.

*我正在使用WebForms.

如果您必须自己调用Web服务,可以HttpClient 按照Henrik Neilsen的说明尝试使用.

更新了HTTPClient示例

一个基本的例子:

// Create an HttpClient instance 
HttpClient client = new HttpClient(); 

// Send a request asynchronously continue when complete 
client.GetAsync(_address).ContinueWith( 
    (requestTask) => 
    { 
        // Get HTTP response from completed task. 
        HttpResponseMessage response = requestTask.Result; 

       // Check that response was successful or throw exception 
        response.EnsureSuccessStatusCode(); 

        // Read response asynchronously as JsonValue
        response.Content.ReadAsAsync<JsonArray>().ContinueWith( 
                    (readTask) => 
                    { 
                        var result = readTask.Result
                        //Do something with the result                   
                    }); 
    });

您应该将逻辑重构为一个单独的后端类,并直接从您的代码隐藏和Web API操作中调用它.
