今天通过本文给大家分享C#中API调用的多种方法，通过API进行解析扫入的二维码，实例代码给大家介绍的非常详细，需要的朋友参考下吧

介绍

API( Application Programming Interface ),我想大家不会陌生,它是我们Windows编程的常客,虽然基于.Net平台的C#有了强大的类库,但是,我们还是不能否认API在Windows编程中的重要性.大多数的编程语言都支持API编程,而.Net平台中的MFC(Microsoft Foundation Class Library)构架本身就封装了大部分的API.

做为程序员,我们需要了解API从字面上了解便是编程接口,因此,做为开发者,需要了解的只是API的使用方法.

API根据操作系统、处理器及功能性的不同而拥有很多不同的类型. 操作系统特用的API:

每种操作系统都有许多通用的API以及一些特用的API,这些特用的API只能在当前操作系统中执行.

方式1

									//通过API进行解析扫入的二维码

									               string CodeMsg = HttpPost("http://eap2mes:8088/App/ExecuteProcedure?", "EventType=APP_REELIDSPLIT&InputJson=" + "{CODE:\"" + newCodeText + "\"}");

									               System.Diagnostics.Debug.WriteLine(CodeMsg);

									      public static string HttpPost(string url, string body)

									       {

									           Encoding encoding = Encoding.UTF8;

									           HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

									           request.Method = "POST";

									           request.Accept = "text/html, application/xhtml+xml, */*";

									           request.ContentType = "application/x-www-form-urlencoded";

									           byte[] buffer = encoding.GetBytes(body);

									           request.ContentLength = buffer.Length;

									           request.GetRequestStream().Write(buffer, 0, buffer.Length);

									           HttpWebResponse response = (HttpWebResponse)request.GetResponse();

									           using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))

									           {

									               return reader.ReadToEnd();

									           }

									       }

方式2

				?

									/// 执行 存储过程

									                /// 返回Json字符串 { "Result": "OK", "Msg": "", "Return_Data": "" } OR { "Result": "NG", "Msg": "Error Msg", "Return_Data": "" }

									                /// Return_Data : 依存储过程而定，可以是独立基础型字符串，也可以是Json格式字符串

									                JObject JObj = new JObject();

									                JObj.Add("FunctionID", "REELID-SPLIT");

									                JObj.Add("CODE", "20210605141700254036@004.078.0050010@119414@@21231@20210605@9000");

									                string CodeMsg = Utility.ExecuteProcedure(JObj.ToString());

									                System.Diagnostics.Debug.WriteLine(CodeMsg);
