如何通过WebRequest发送较大的post字符串数据？

string data = "Your large post data here";
int chunkSize = 1024; // 设置每个数据块的大小

// 设置请求的URL和方法
WebRequest request = WebRequest.Create("https://example.com/api");
request.Method = "POST";
request.ContentType = "text/plain"; // 设置内容类型

// 拆分数据为较小的块
int totalChunks = (int)Math.Ceiling((double)data.Length / chunkSize);

// 逐个发送数据块
for (int chunkIndex = 0; chunkIndex < totalChunks; chunkIndex++)
{
    // 获取当前数据块
    string chunkData = data.Substring(chunkIndex * chunkSize, Math.Min(chunkSize, data.Length - chunkIndex * chunkSize));

    // 创建用于写入请求流的StreamWriter
    using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
    {
        // 将数据块写入请求流
        writer.Write(chunkData);
    }
    
    // 发送请求并获取响应
    using (WebResponse response = request.GetResponse())
    {
        // 处理服务器响应
        // ...
    }
}
