C# Code:

string url = "http://localhost:8899/api/testapi/get-by-model";

ModelRequest M = new ModelRequest();
M.ActionID = 100000;
M.ApiKey = "5cd31880a3f548ee9a8f37768bd6ebc8";
M.Data = "使用HttpGet方法接受实体类参数演示";
M.Sign = "s34df15cd31880a3f548ee9a8f37768bd6ebc8";

string JSON = JsonConvert.SerializeObject(M);
string result = WebApiTools.Get(url, JSON);

txtResponse.Text = result;
