將VB文本轉(zhuǎn)換為數(shù)值型的方法是使用VB中的內(nèi)置轉(zhuǎn)換函數(shù)或方法,如CInt、CDbl、CDec、CSng等。這些函數(shù)可以將文本字符串轉(zhuǎn)換為整數(shù)、雙精度浮點數(shù)、十進(jìn)制數(shù)、單精度浮點數(shù)等數(shù)值類型。
以下是常用的VB文本轉(zhuǎn)化為數(shù)值型的方法示例:
Dim text As String = "123"
Dim number As Integer = CInt(text)
Dim text As String = "3.14"
Dim number As Double = CDbl(text)
Dim text As String = "10.5"
Dim number As Decimal = CDec(text)
Dim text As String = "2.5"
Dim number As Single = CSng(text)
以上示例中,將文本字符串賦給一個變量,然后使用相應(yīng)的轉(zhuǎn)換函數(shù)將文本轉(zhuǎn)換為對應(yīng)的數(shù)值類型,并將轉(zhuǎn)換后的結(jié)果賦給另一個變量。
