a=x.indexof("[")
x=x.substring(0,a)"0"x.substring(b)
VB.NET 2010 如何替换两个固定字符串之间的变量这个简单vb.net替换制定字符，截取字符串就行vb.net替换制定字符了

vb.Net对文件指定字符串的修改文本框 TextBox1
上一条 Button1
下一条 Button2
修改 Button3
Imports System.IO
Public Class Form1
Dim currIndex As Integer = 0
Dim s2 As List(Of String) = New List(Of String)
Dim s As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
s = File.ReadAllText(Application.StartupPath"\txt.txt")
Dim s1 As String() = s.Split("@")
For i As Integer = 0 To s1.Length - 1
If s1(i).Trim()"" Then
s2.Add("@"s1(i))
End If
Next
TextBox1.Text = s2(0)
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
currIndex = currIndex + 1
If currIndexs2.Count - 1 Then
MsgBox("已经是最后条了")
Return
End If
TextBox1.Text = s2(currIndex)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
currIndex = currIndex - 1
If currIndex0 Then
MsgBox("已经是第一条了")
Return
End If
TextBox1.Text = s2(currIndex)
End Sub
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
s2(currIndex) = TextBox1.Text
s = ""
For i As Integer = 0 To s2.Count - 1
s = s2(i)

vb.net 读取txt 并替换指定字符串问题语法错误 ， 没有存储函数的返回值 。
temp.Replace("111", "22")
这个函数方法返回修改后的结果，并不修改参数变量本身 ， 也就是按值传递 ， 而不是按地址传递，正确用法：
temp=temp.Replace("111", "22")
用VB.NET快速替换DLL文件中的字符串将dll以文件方式以UTF-8的方式读入，然后接下来就替换字符串就可以了嘛
C#:
using System.IO;
...
string text;
text=File.ReadAllText(FilePath, Encoding.UTF8);
text.Replace("...","...");
...
-------------------------
还要谢谢你 ， 不然我还不知道是UTF-8的编码格式，我有一个验证的问题可以解决了 。
