推荐答案

RichTextBox1.Text = "test@{test.fr}"
Dim i As Integer = RichTextBox1.Text.LastIndexOf("@{")
Dim s As String = RichTextBox1.Text.Substring(i, RichTextBox1.Text.LastIndexOf("}") - i + 1)
MessageBox.Show(s)

Public Class Form1

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        RichTextBox1.Text = "test@{test.fr}"
        Dim i As Integer = RichTextBox1.Text.LastIndexOf("@{")
        Dim s As String = RichTextBox1.Text.Substring(i+2, RichTextBox1.Text.LastIndexOf("}") - (i+2))
        MessageBox.Show(s)

    End Sub

End Class

此代码在MessageBox中返回test.fr。所以，@ {和}之间的值。

This code returns "test.fr" in the MessageBox. So, the value between "@{" and "}".
