~!String(數(shù)字,字符)是VB的內(nèi)置函數(shù),它的功能是創(chuàng)建一個字符串。在這個函數(shù)中,character——要生成的字符數(shù)——字符數(shù),例如private sub command1u Click()dim s as string s=string(20,dim)“a”)msgbox s End Sub運行結(jié)果為:s=“aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa如果將character設(shè)置為字符串,則string()函數(shù)只讀取字符串的第一個字符。例如,private sub command1u Click()dim s as string s=string(20,“ABC”)msgbox s End sub仍以:s=“aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
