警告访问process.start（）的共享成员 [英] warning access of a shared member for process.start()

问题描述

大家好，



我使用以下代码从文件夹中打开文件，当我使用process.start时，我收到了共享的警告访问权限成员，常量成员，通过实例的枚举成员，不会评估限定表达式，并且行 p.start（fname）以绿色下划线以绿色突出警告。



有人请帮忙删除这个，



提前致谢!!!

Hi All,

I use the below code to open a file from a folder and when i use process.start, i am getting a warning access of shared member,constant member, enum member through an instance, qualifying expression will not be evaluated and the line p.start(fname) gets zigzag underlined in green color throwing the warning.

Could someone please help to remove this,

Public Class _Default
    Inherits System.Web.UI.Page
    Dim path As String = ConfigurationManager.AppSettings("filepath")
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            If (Not IsPostBack) Then
                Dim di As DirectoryInfo = New DirectoryInfo(path)
                Dim fidir As FileInfo() = di.GetFiles()
                Dim fi As FileInfo
                For Each fi In fidir
                    lstbx_file.Items.Add(fi.FullName)
                Next
            End If        
    End Sub

    Protected Sub lstbx_file_SelectedIndexChanged(sender As Object, e As EventArgs) Handles lstbx_file.SelectedIndexChanged
            Dim fname As String
            Dim x As New _Default
            fname = System.IO.Path.Combine(x.path, lstbx_file.SelectedValue.ToString())
            Dim p As New Process()
            p.Start(fname)
            p.Close()
            p.Dispose()
    End Sub
End Class

推荐答案

不要这样做;

Do not do this;

Dim p As New Process()
p.Start(fname)
p.Close()
p.Dispose()

这样做，而不是;

Do, this instead;

Dim p As Process = Process.Start(fname)
p.WaitForExit() ' Might want to use a timeout here
p.Dispose()

希望这个帮助，
