-- [求助]腾讯云的回调函数如何接受? 已解决!
vb.net 代码如下:
uploadTask.progressCallback = delegate (long completed, long total)
{
Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total));
};
不明白这个如何接收.
正确代码:
Dim progress As cosxml.Callback.OnProgressCallback = Function(completed , total)
Output.Show( completed & " " & total)
End Function
uploadTask.progressCallback = progress

加上后,报这个错误,我该如何修改?
.NET Framework 版本：4.0.30319.42000
Foxtable 版本：2022.8.18.1
错误所在事件：自定义函数,cos_文件_上传
详细错误信息：
调用的目标发生了异常。
从类型“VB$AnonymousDelegate_0(Of Long,Long,Object)”到类型“OnProgressCallback”的转换无效。
uploadTask.progressCallback = Function(ByVal completed As Long, ByVal total As Long) Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total)) End Function |

试试
Dim progress As OnProgressCallback = Function(completed , total) Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total))
uploadTask.progressCallback = progress
或者
uploadTask.progressCallback == Function(completed , total) Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total))

以下是引用有点蓝在2024/4/2 11:11:00的发言：

试试
Dim progress As OnProgressCallback = Function(completed , total) Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total))
uploadTask.progressCallback = progress
或者
