Visual Basic 2010如何在字符串中查找“ =”

Question

string = "I was born in = 1994"

如何将所有“ =”之后的值存储在变量中？

Answer 1

这是最简单的方法：

Dim var = s.Substring(s.IndexOf("="c) + 1)

Answer 2

您可以使用拆分功能：

  Dim [string] = "I was born in = 1994"
  Dim temp() As String = Split([string], " = ", -1, CompareMethod.Binary)
  'now value is in temp(1)
  MessageBox.Show(temp(1))

Answer 3

有很多方法，我将在字符串中使用。

mystring as new string
mystring  = "I was born in =1994"
DataAfterEquals as string = mid(mystring,instr(mystring,"=")+1,mystring.length-instr(mystring,"=")+1)

您当然可以使用正则表达式，使用拆分，然后当然可以采用旧的方式并遍历字符串以查找等号。

上面的代码将找到第一个等号，然后从字符串中的该点向外解析，因此我添加了+1以跳过等号。 此伪代码。
