vb.net中替换的代码 vb文本替换

请问在VB.NET中如何去除 这个空格你是要把连续多个空格vb.net中替换的代码 , 变换成只需要一个空格vb.net中替换的代码,那么vb.net中替换的代码:
do while Instr(tStr,"")0
tStr = Replace(tStr, "", " ") '用一个空格 , 替换2个空格
loop
求VB.NET对任一excel表格查找替换的代码 。Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'On Error GoTo EXIT_ERROR
Dim strErrorPos As String = "F_TreatOne"
Dim strFileName As String
strFileName = "d:\test.xlsx"
Dim objExcelApp As New Microsoft.Office.Interop.Excel.Application
Dim objWorkBook As Microsoft.Office.Interop.Excel.Workbook
Dim objSheet As Microsoft.Office.Interop.Excel.Worksheet
objWorkBook = objExcelApp.Workbooks.Open(strFileName)
objSheet = objWorkBook.Worksheets(1)
objSheet.UsedRange.Replace("aaa", "bbb")
objWorkBook.Save()
objWorkBook.Close()
objExcelApp.Quit()
objWorkBook = Nothing
objExcelApp = Nothing
End Sub
需要的话,自已再适当修改修改.
项目中需要加对Microsoft.Office.Interop.Excel的引用.
vb.net 替换word文本框中的字符 点击替换按钮时内容中的a替换为b,c替换为d 怎么操作? 需要代码 。直接用Replace语句把:
Dim oldstr,newstr as string
oldstr="abcdeftgd"
newstr=replace(oldstr,"a","b")
newstr=replace(newstr,"c","d")
望采纳 。
vb.net正则表达式 替换内容@interface不替换的话,就把正则改成:
@(?!interface)[^\s]+(\s|$)
如果@t3(synopsis = "AB") 这个等号前后没有空格,就很简单,直接用下面的搞定,如果有空格,这个正则就会复杂很多了:
Regex.Replace(@"@t1
@t2()
@t3(synopsis=""AB"")
@t4(""unused"")
creatCommChat(@WebParam(name=""chatID"") String chatID,@WebParam(name=""creatUserID"") String creatUserID)", @"@[^\s]+(\s|$)", "")
