向同一接口发出100个请求后，C# RestSharp RestClient失败

var client = new RestClient("http://example.com");
client.Timeout = 60000; // 设置为60秒

var tasks = new List<Task>();
for (int i = 0; i < 100; i++)
{
    tasks.Add(client.ExecuteAsync(new RestRequest("endpoint")));
}

await Task.WhenAll(tasks);

var semaphore = new SemaphoreSlim(10); // 最多同时处理10个请求
var tasks = new List<Task>();
for (int i = 0; i < 100; i++)
{
    await semaphore.WaitAsync();
    tasks.Add(client.ExecuteAsync(new RestRequest("endpoint")).ContinueWith(t =>
    {
        semaphore.Release();
    }));
}

await Task.WhenAll(tasks);

public async Task ExecuteWithRetry(IRestRequest request, int maxRetries = 3)
{
    for (int i = 0; i < maxRetries; i++)
    {
        var response = await client.ExecuteAsync(request);
        if (response.StatusCode == HttpStatusCode.OK)
            return response;
        await Task.Delay(1000); // 等待1秒后重试
    }
    throw new Exception("请求失败，达到最大重试次数");
}
