                    (InvoiceDate) as [Invoice Date],
                    (Sales.CustomerID) as [Customer ID],
                    (CustomerName) as [Customer Name],
                    (GrandTotal) as [Grand Total],
                    (TotalPayment) as [Total Payment],
                    (PaymentDue) as [Payment Due] 
                    from Sales,Customer 
                        where 
                           Sales.CustomerID=Customer.CustomerID 
                        and 
                           InvoiceDate between #" + DateTimePicker2.Text + "# And #" + DateTimePicker1.Text + "# and PaymentDue > 0 
                        order by 
                           InvoiceDate desc", con);

【问题讨论】：

格式化？问题在哪里？你试过什么？

您使用哪种 DBMS？我把你的# 稀释成'。
# 用于 JET 而不是 T-SQL。只需使用参数，就不必连接字符串，让自己对 SQL 注入敞开心扉。这不是 PHP。
SQL 是一种查询语言。它不是数据库产品的名称。每个关系数据库（Oracle、Postgres、DB2、Firebird、Microsoft SQL Server 等）都是“SQL 数据库”

【解决方案1】：

如果您使用TSQL，我认为您应该将date 作为字符串传递。但是，我不确定您是否需要任何时间部分，您可能需要修改tostring中的格式

cmd = new SqlCommand("SELECT 
                    (invoiceNo) as [Invoice No],
                    (InvoiceDate) as [Invoice Date],
                    (Sales.CustomerID) as [Customer ID],
                    (CustomerName) as [Customer Name],
                    (GrandTotal) as [Grand Total],
                    (TotalPayment) as [Total Payment],
                    (PaymentDue) as [Payment Due] 
                    from Sales,Customer 
                        where 
                           Sales.CustomerID=Customer.CustomerID 
                        and 
                           InvoiceDate between '" + DateTimePicker2.Value.ToString("yyyyMMdd") + "' 
                        And '" + DateTimePicker1.Value.ToString("yyyyMMdd") + "' and PaymentDue > 0 
                        order by 
                           InvoiceDate desc", con);
