partnumber

For instance , components from one source might use a PartNumber type , while components from another source use a PartNum type .

例如，来自一个源的组件可能使用PartNumber类型，而来自另一个源的组件使用PartNum类型。

Without the type-checking , you can wire anything to anything , for example , CustomerName to a PartNumber , even if doing so makes no sense .

可以在不用进行类型检查的情况下进行任意连接，即使这样做毫无意义。
