在Visual Basic (VS2019)中,可以通过以下步骤将CheckedListBox中的多个选定项添加到SQL表中:
Dim connection As New SqlConnection("YourConnectionString")
Dim command As New SqlCommand("SELECT * FROM YourTable", connection)
Dim adapter As New SqlDataAdapter(command)
Dim table As New DataTable()
adapter.Fill(table)
CheckedListBox1.DataSource = table
CheckedListBox1.DisplayMember = "ColumnName"
CheckedListBox1.ValueMember = "ColumnID"
请将"YourConnectionString"替换为您的SQL数据库连接字符串,"YourTable"替换为您要从中获取数据的表名,"ColumnName"替换为您要显示在CheckedListBox中的列名,"ColumnID"替换为您要作为值存储的列名。
Using connection As New SqlConnection("YourConnectionString")
connection.Open()
For Each item As DataRowView In CheckedListBox1.CheckedItems
Dim command As New SqlCommand("INSERT INTO YourTable (Column1, Column2) VALUES (@Value1, @Value2)", connection)
command.Parameters.AddWithValue("@Value1", item("Column1"))
command.Parameters.AddWithValue("@Value2", item("Column2"))
command.ExecuteNonQuery()
Next
connection.Close()
End Using
请将"YourConnectionString"替换为您的SQL数据库连接字符串,"YourTable"替换为您要插入数据的表名,"Column1"和"Column2"替换为您要插入的列名。
以上代码将遍历CheckedListBox中的选定项,并使用参数化查询将它们插入到SQL表中。
注意:在实际应用中,应根据您的具体需求进行适当的修改和错误处理。
