Question

我想创建一个标签页面，如附图所示。条形码与标签“PT01-0000011”具有相同的描述，并添加*，因此“* PT01-0000011 *”。

到目前为止，问题是我希望第二个标签有“PT01-0000012”，第三个“PT01-0000013”......“PT01-00000XX”。

我留下数据库的脚本，并使用C＃。

SQL

Answer 1

您需要将标签的一部分解析为int

var currentLabel = int.Parse（cmd1.ExecuteScalar（）。ToString（））;

并且在您需要时使用它而不是label2.Text，因为它具有string值。每当你需要再次将其转换为sting时，我猜你需要一个前导空值，以便你可以使用

currentLabel.ToString（ “D7”）

创建C＃Hang标签4x12
