我收到System.ArgumentOutOfRangeException错误

Question

我在vb.net中得到了这段代码

    Imports RasterEdge.Imaging.Basic.TextSearch
    Imports RasterEdge.XDoc.PDF




    Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    'Open a document
    Dim doc As PDFDocument = New PDFDocument(Application.StartupPath & "/Vertrag.pdf")

    'Set the search options
    Dim options As RESearchOption = New RESearchOption()
    options.IgnoreCase = False
    options.WholeWord = False

    'Replace "RasterEdge" with "Image"
    doc.Replace("#Name", "#Lame", options)   <-- Here i get the error
    doc.Save(Application.StartupPath & "/testoutput.pdf")


    End Sub
    End Class

我标记了弹出 System.ArgumentOutOfRangeException 错误的位置。

所有这些都使用RasterEdge dlls用另一段文本替换一段文本（#Name - ＆gt; #Lame（只是一个测试））

你们有什么想法吗？
