VB.NET 读取和编辑 SHX 文件示例代码 - 完整指南

以下是一个示例代码，用于读取和编辑.shx文件：\n\nvb.net\nImports System.IO\n\nModule Module1\n Sub Main()\n Dim shxFilePath As String = "path_to_shx_file.shx"\n\n ' 读取.shx文件\n Dim records As List(Of ShxRecord) = ReadShxFile(shxFilePath)\n\n ' 遍历.shx文件记录\n For Each record As ShxRecord In records\n Console.WriteLine("Offset: " & record.Offset)\n Console.WriteLine("Content: " & record.Content)\n Console.WriteLine()\n Next\n\n ' 编辑.shx文件记录\n EditShxFile(shxFilePath, 2, "New content")\n\n ' 重新读取.shx文件\n records = ReadShxFile(shxFilePath)\n\n ' 遍历.shx文件记录\n For Each record As ShxRecord In records\n Console.WriteLine("Offset: " & record.Offset)\n Console.WriteLine("Content: " & record.Content)\n Console.WriteLine()\n Next\n\n Console.ReadLine()\n End Sub\n\n ' 读取.shx文件\n Function ReadShxFile(filePath As String) As List(Of ShxRecord)\n Dim records As New List(Of ShxRecord) ()\n\n Using fs As New FileStream(filePath, FileMode.Open, FileAccess.Read)\n Using br As New BinaryReader(fs)\n br.BaseStream.Seek(0, SeekOrigin.Begin)\n\n While br.BaseStream.Position < br.BaseStream.Length\n Dim offset As Integer = br.ReadInt32()\n Dim contentLength As Integer = br.ReadInt32()\n Dim contentBytes As Byte() = br.ReadBytes(contentLength)\n Dim content As String = System.Text.Encoding.UTF8.GetString(contentBytes)\n\n Dim record As New ShxRecord(offset, content)\n records.Add(record)\n End While\n End Using\n End Using\n\n Return records\n End Function\n\n ' 编辑.shx文件\n Sub EditShxFile(filePath As String, recordIndex As Integer, newContent As String)\n Dim records As List(Of ShxRecord) = ReadShxFile(filePath)\n\n If recordIndex >= 0 AndAlso recordIndex < records.Count Then\n records(recordIndex).Content = newContent\n\n Using fs As New FileStream(filePath, FileMode.Create, FileAccess.Write)\n Using bw As New BinaryWriter(fs)\n For Each record As ShxRecord In records\n bw.Write(record.Offset)\n Dim contentBytes As Byte() = System.Text.Encoding.UTF8.GetBytes(record.Content)\n bw.Write(contentBytes.Length)\n bw.Write(contentBytes)\n Next\n End Using\n End Using\n End If\n End Sub\nEnd Module\n\nClass ShxRecord\n Public Property Offset As Integer\n Public Property Content As String\n\n Public Sub New(offset As Integer, content As String)\n Me.Offset = offset\n Me.Content = content\n End Sub\nEnd Class\n\n\n请注意，这只是一个示例代码，根据实际情况可能需要进行适当的修改和调整。
