一般遇到字符串还要去掉引号,通常是指原字符串中含有引号没法赋值
如123“456”789,如果写成Dim a As String = "123"456" 789"肯定不行,可以写成Dim a As String = "123" Chr(34) "456" Chr(34) "789"
a="""123"""
'去掉如下
a=replace(a,"""","")
'主要涉及双引号的转义
因为VB.NET的源码中字符串常量是用英文双引号开始和结束的,如:"abc",如果要显示引号,输入"""是错误的,要4个英文双引号才能显示一个正确的英文双引号,如:MsgBox("""")。
技术工具箱: VB.NET, XML, ADO.NET ADO.NET提供了一种很好的功能来处理dataset和XML之间的转换。你可以通过VS.NET在XML中形象地创如何解决CSV字段数据的双引号问题,主要解决CSV字段数据带有双引号的问题 具体代码如下:以下为引用的内容:Public Function ChangeCsvSplitLine(ByVal strLine As String, ByVal iColNumber As Integer) As String() Dim strList() As String = strLine.Split(",") If strList.Length = iColNumber Then Return strList End IfDim i As Integer = 0 Dim findSplitIndex As Integer = -1 Dim index As Integer = 0 Dim returnList(iColNumber) As String Dim strMerger As String = "" For i = 0 To strList.Length - 1 If findSplitIndex = -1 Then If (strList(i)(0) = """" And strList(i)(strList(i).Length - 1) """") _ Or (strList(i).Length = 1 And strList(i) = """") Then findSplitIndex = iElsereturnList(index) = strList(i) index = index 1End IfElseIf (strList(i)(0) """" And strList(i)(strList(i).Length - 1) = """") _ Or (strList(i).Length = 1 And strList(i) = """") Then strMerger = ""
