本文主要是介绍如何用RestClient 请求带参数的服务，请求服务为某翻译API

直接上源码

1.Nuget添加RestSharp包

Install-Package RestSharp -Version 107.3.0

2.使用RestClient发送请求

public static void Fanyin_RestClient(string fromString)
{
	Console.WriteLine($"Fanyin_RestClient post");
	var client = new RestClient(ApiConfig.Url);
	var request = new RestRequest("POST");

	request.AddHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");

	string randnum = Random.Shared.Next(100).ToString();
	string sign = Encrypt.EncryptString(ApiConfig.ApiId + fromString + randnum + ApiConfig.ApiKey);

	request.AddParameter("q", fromString);
	request.AddParameter("from", Language.中文简体);
	request.AddParameter("to", Language.英语);
	request.AddParameter("appid", ApiConfig.ApiId);
	request.AddParameter("salt", randnum);
	request.AddParameter("sign", sign);

	var response = client.ExecuteAsync(request);
	Console.WriteLine(response.Result.Content);
}

3.输出
