问题描述
我有一个固定长度的字符串变量:
I have a fixed length string variable:
<VBFixedString(10)>
Public myVar As String
当我将 var 分配给具有 11 个字符的值时，var 会改变长度.
When I assign the var to a value that has 11 chars the var changes length.
这是我得到的:
myvar = "1234567890ABCD" ' result = myvar being "1234567890ABCD"
我想要的是 myvar 是:1234567890"
What I want is myvar to be: "1234567890"
然后如果它小于 10 我想要
and then if it is less than 10 I would like
myvar = "12345" to be "12345 "
我可以用 PadLeft PadRight 做到这一点，但想知道我是否可以将它声明为固定长度，它会为你处理所有这些.
I can do this with PadLeft PadRight but was wondering if I can declare it as a fixed length and it would handle all that for you.
推荐答案
和老派一样，LSET 将完全满足您的要求.
and from the old school, LSET will do exactly what you're asking.
myvar = lset("1234567890ABCD",10)
结果为1234567890"，而
results in "1234567890", while
myvar = lset("12345",10)
结果为12345___" - 抱歉，编辑器在将 12345 替换为下划线后修剪了空格
results in "12345___" - sorry, the editor trimmed the spaces after the 12345 replaced with underscores
请参阅 LSET 的 MSDN 条目
