vb.net：将二进制文件读入项目
我试图在.exe关闭时将项目属性保存到文件中，并在.exe再次打开时重新加载它们。我尝试保存为.xml，但引发了异常，因此我尝试保存为二进制文件，如下所示：vb.net：将二进制文件读入项目,vb.net,binary,filestream,Vb.net,Binary,Filestream,我试图在.exe关闭时将项目属性保存到文件中，并在.exe再次打开时重新加载它们。我尝试保存为.xml，但引发了异常，因此我尝试保存为二进制文件，如下所示： Dim savedProject As New classProject savedProject = project Dim fileName As String fileName = project.name Using fs As New System.IO.FileStream(project.directory & "
Dim savedProject As New classProject
savedProject = project
Dim fileName As String
fileName = project.name
Using fs As New System.IO.FileStream(project.directory & "\" & project.name & ".bin", IO.FileMode.OpenOrCreate, FileAccess.Write)
Dim bf As New BinaryFormatter
bf.Serialize(fs, savedProject)
End Using
在这个论坛的帮助下，我在网上看到了很多关于如何以这种方式保存到文件的例子，但是我很难找到如何在重新加载.exe时重新加载这个文件 您可以使用我的通用用法序列化片段从Xml或二进制文件进行序列化和反序列化 示例用法如下：
Dim obj As String() = {"Hello World!"}
SerializationUtil.Serialize(obj, "C:\File.bin", SerializationFormat.Binary)
obj = SerializationUtil.Deserialize(Of String())("C:\File.bin", SerializationFormat.Binary)
