VB.net 字串格式 Format

Format是VB.Net中很好用,不需死記參數,很人性化的格式化Function,舉例:

123456789 (三位一撇千分位)

Format(123456789, "###,###")    OutPut ; 123,456,789

0.2666666 (小數點後兩位,四捨五入,並加上%)

Format(0.2666666,"0.00%")         OutPut  : 26.67%

 千分位,小數點捨去

Format(Val(strValue.ToString), "###,##0")

VB.net 一次控制全部元件(TextBox等)

        Dim Command1() As TextBox = _
            {tbPanel1, tbPanel2, tbPanel3, tbPanel4, tbPanel5, tbPanel6, tbPanel7, tbPanel8, tbPanel9, tbPanel10}

            If ComboBox9.SelectedIndex >= i Then

                Command1(i).Visible = True

            Else

VB.net 拆字串 分割字串 切字串

text.Split(",")



Dim strMember1 As String() = strTemp.Split(vbCrLf)    '分行切割

Dim strMember2 As String() = strMember1(intSelected).Split(",")

        strMember3(intSelected) = strMember2(0).Trim()   '去空白 姓名
        TextBox1.Text = strMember3(intSelected)

VB.net 去空白 去換行

.Trim()

strMember3(intSelected) = strMember2(0).Trim()   '去空白 姓名

VB.net 換行符號(vbcrlf)

換行符號: vbcrlf

Tab: vbTab
