C#初始化数据库错误提示:The type initializer for 'ASSET.DBHelper' threw an exception

年末总结7
这是我在做ASSET工程时,DBHelper.cs不管用了,也就是数据库连不上了。
问题出在初始化数据库错误,导致下方的sql语句不能执行,得出的result值为null

 public static int ExecuteSql(string sql)
        {
            cn.Open();
            SqlCommand cmd = new SqlCommand(sql,cn);
            int result = cmd.ExecuteNonQuery();
            cn.Close();

            return result;
        }

解决方法:回头看看数据库连接语句

Data Source = localhost;Integrated Security = SSPI;Initial Catalog = Module_4_DB;//分号隔开

以上。

UNet 改进(27):结合SCSE注意力机制的UNet网络实现

本文介绍了一种结合SCSE注意力机制的改进UNet网络架构。该网络在保持UNet经典编码器-解码器结构基础上,通过在每层添加SCSEBlock模块,融合了通道注意力和空间注意力机制。通道注意力通过全局池化和1×1卷积生成通道权重,空间注意力则产生空间权重图,二者相加增强关键特征响应。该设计具有以下优势:1)保持原始UNet的多尺度特征提取能力;2)通过注意力机制提升对重要区域的关注度;3)计算效率高,仅增加少量参数。测试显示网络能保持输入输出分辨率不变,适用于医学图像分割等像素级预测任务。完整代码实现了5层
