标题: c# 调用文心一言大模型
注册账号

1.注册（百度智能云）

2.选择应用接入

3.创建应用接口

4.获取 API_KEY与 SECRET_KEY

代码实现

实现前先要在NuGet程序包下载两个库
Newtonsoft.Json;（我现在使用版本13.0.3）
RestSharp；（我现在使用版本106.2.0）
已下是代码的实现
namespace WindowsFormsApp1
{
public partial class Form1 : Form
{
您的AccessKey ID
//const string API_KEY = "OA6CUefHaF7CkTLc9k8KdWwu";
您的AccessKey Secret
//const string SECRET_KEY = "zlYO2QF641jVGqIlT0Hv31stYISvh6nj";
// 您的AccessKey ID
const string API_KEY = "AFJFrctHEskWpwGJ2jcGTA0s";
// 您的AccessKey Secret
const string SECRET_KEY = "Y59b4iZMBTjfWtSHXR01JQfG0dX2rOif";
//文心一言会根据前面的问答回复信息
