类文件怎样读取配置文件里的信息？

[lin_lin]

我有一个类，编成dll后要放到服务器上单独运行，现在想把它其中的一些参数提出来，配在外面。就像工程中调用web.config一样，好像记得有解决的方法，记不起来了：）

[巍巍清风]

自己写一个读取配置文件的类，可以指定配置文件名，读取里面的参数。
我有一个，要吗？

谢谢大家！我觉得还不如读取一个文本文件简单：）
我再试一下，回来给分。

是用序列化，很反序列化方式做看
XmlSerializer类

自己写个XML文档解析算法解析你的XML配置文件。

找了一段代码操作web.config:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'在此处放置初始化页的用户代码
logo.Title = "服务器配置"
dtstConfig = Session("dtstConfig")
If dtstConfig Is Nothing Then
dtstConfig = New DataSet()
dtstConfig.ReadXml(MapPath("Web.Config"))
Session("dtstConfig") = dtstConfig
End If
If Not IsPostBack Then
GridDataBind()
End If
'Response.Write(SystemFramework.ApplicationConfiguration.CancelOrderPrintLines())
End Sub
Sub GridDataBind()
dgrdConfig.DataSource = dtstConfig.Tables("Add")
dgrdConfig.DataBind()
End Sub
Private Sub dgrdConfig_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgrdConfig.EditCommand
dgrdConfig.EditItemIndex = e.Item.DataSetIndex
GridDataBind()
End Sub
Private Sub dgrdConfig_CancelCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgrdConfig.CancelCommand
dgrdConfig.EditItemIndex = -1
GridDataBind()
End Sub
Private Sub dgrdConfig_UpdateCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgrdConfig.UpdateCommand
Dim txtCurrent As TextBox
Dim strValue As String
txtCurrent = e.Item.FindControl("txtValue")
strValue = txtCurrent.Text
dtstConfig.Tables("Add").Rows(e.Item.DataSetIndex).Item("Value") = Trim(txtCurrent.Text)
dtstConfig.AcceptChanges()
Session("dtstConfig") = dtstConfig
dgrdConfig.EditItemIndex = -1
GridDataBind()
End Sub
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
dtstConfig.WriteXml(MapPath("Web.Config"))
End Sub
End Class

用反射（reflection）它是程序读取自身原数据的过程
程序自我反射是它从配件中提取元数据

public static void Main()
{
MyMath mm = new MyMath();
Console.WriteLine("Calling DoFunc(7).Result:{0}",mm.DoFuncl(7));

//获取成员信息并用它来，获取自定义属性信息
System.Reflection.MemberInfo inf = typeof(MyMath);
object[] attributes;
attributes = inf.GetCustomAttributes(typeof(BugFixAttribute).false);

//遍历属性信息获取性质
foreach(Object attribute in attributes)
{
BugFixAttribute bfa = (BugFixAttribute)attribute;
Console.WriteLine("\nBugID:{0}",bfa.BugID);
Console.WriteLine("Programmer: {0}",bfa.Programmer);
Console.WriteLine("Date: {0}",bfa.Date);
Console.WriteLine("Comment: {0}",bfa.Comment);
}
}
