如何檢測字符串出現(xiàn)的次數(shù)？

Function CheckTheChar(TheChar,TheString)
' TheChar="要檢測的字符串".
' TheString="待檢測的字符串".
if inStr(TheString,TheChar) then
for n =1 to Len(TheString)
if Mid(TheString,n,Len(TheChar))=TheChar then
CheckTheChar=CheckTheChar+1
End if
Next
CheckTheChar="這個字符"&CheckTheChar&"次"
else
CheckTheChar="0次"
end if
End Function
