System.Data.SqlClient.SqlException：将varchar值“ Images / win.jpg”转换为数据类型int时转换失败

问题描述

我正在使用aspx .net 2012，并且遇到此错误： System.Data.SqlClient.SqlException：将varchar值'Images / win.jpg'转换为数据类型int时转换失败

。

employee.setEmployeeDepartmentList(Arrays.asList(employeeDepartment));

我的错误正好在 SqlCommand cmd行

的第一个 else 语句中

以下是该代码：
