lstrcmpi

說明:
lstrcmpi 函式可比對兩字串的大小,但不會比對字母的大小寫


引用函式庫:
Kernel32


適用系統:
Windows NT 3.1 或 Windows 95以上


函式原型:

Declare Function lstrcmpi Lib "kernel32" Alias "lstrcmpiA" ( _
    ByVal lpString1 As String, _
    ByVal lpString2 As String _
    ) As Long



參數型態及說明:
lpString1String 第一個要比對的字串
lpString2String 第二個要比對的字

回傳值:
LonglpString1 大於 lpString2 時,則回傳正值(1);若 lpString1 小於 lpString2 時,則回傳負值(-1);若 lpString1 等於 lpString2 時,則回傳零(0)

.NET Framework API:
System.String.Compare
System.String.Equals
