如何读取membership中配置节的属性

Question

比如:
<membership defaultProvider="AspNetSqlProvider">
      <providers>
        <add connectionStringName="AppConnectionString" applicationName="/" description="" minRequiredPasswordLength="3" minRequiredNonalphanumericCharacters="0" requiresUniqueEmail="false" enablePasswordRetrieval="false" enablePasswordReset="false" requiresQuestionAndAnswer="false" passwordFormat="Hashed" name="AspNetSqlProvider" type="System.Web.Security.SqlMembershipProvider" />
      </providers>如何读取applicationName,description,minRequiredPasswordLength等值的集合?

Answer 1

xmlelement 的属性可以参考这个了。这个例子呢是从code\ASP_NET XML高级编程_C#编程篇\Chapter 02\XMLCategorizer\ 选取的了。如果感兴趣的话，我可以把code打包发给你了。呵呵private void analyzeBtn_ServerClick(object sender, System.EventArgs e)
{
XmlTextReader xmlReader;
XmlValidatingReader xmlDoc = null;
int nElements, gnAttributes, nComments, nPIs, nCDATAs;
String sWorkingText;
nElements = 0;
gnAttributes = 0;
nComments = 0;
nPIs = 0;
nCDATAs = 0;
sWorkingText = "";
resultsArea.InnerText = "";
try
{
xmlReader = new XmlTextReader(fileSelector.PostedFile.InputStream);
xmlReader.WhitespaceHandling = WhitespaceHandling.None;
xmlDoc = new XmlValidatingReader(xmlReader);
xmlDoc.ValidationType = ValidationType.Auto;
XmlUrlResolver resolver = new XmlUrlResolver();
xmlDoc.XmlResolver = resolver;
xmlDoc.ValidationEventHandler += new ValidationEventHandler(this.ValidationEvtCallback);

xmlDoc.Schemas.Add((XmlSchemaCollection)Session["cache"]);

while(xmlDoc.Read())
{
switch (xmlDoc.NodeType)
{
case XmlNodeType.Element:
nElements++;
resultsArea.InnerText += "Element: " + xmlDoc.Name + " has " + xmlDoc.AttributeCount + " attributes\r\n";
gnAttributes += xmlDoc.AttributeCount;
// process the attributes

while (xmlDoc.MoveToNextAttribute())
{
resultsArea.InnerText += "\t" + xmlDoc.Name + "= " + xmlDoc.Value + "\r\n";
}
break;
case XmlNodeType.Text:
sWorkingText = "Text: " + xmlDoc.Value + "\r\n";
resultsArea.InnerText += sWorkingText;
break;
case XmlNodeType.DocumentType:
resultsArea.InnerText += "Document has a DOCTYPE\r\n";
break;
case XmlNodeType.Comment:
nComments++;
resultsArea.InnerText += "Comment: " + xmlDoc.Value + "\r\n";
break;
case XmlNodeType.ProcessingInstruction:
nPIs++;
break;
case XmlNodeType.CDATA:
nCDATAs++;
break;
}
}
sWorkingText = "\r\nTotal number of elements: " + nElements + "\r\n";
sWorkingText += "Total number of attributes in document: " + gnAttributes + "\r\n";
sWorkingText += "Total comments: " + nComments + "\r\n";
sWorkingText += "Total PIs: " + nPIs + "\r\n";
sWorkingText += "Total CDATA sections: " + nCDATAs;
resultsArea.InnerText += sWorkingText;
}
catch (XmlException exc)
{
sWorkingText = "Exception while parsing:\r\n";
sWorkingText += "Line number: " + exc.LineNumber + "\r\n";
sWorkingText += "Line position: " + exc.LinePosition + "\r\n";
sWorkingText += "Message: " + exc.Message + "\r\n\r\n";
sWorkingText += "Stack Trace:\r\n" + exc.StackTrace;
resultsArea.InnerText = sWorkingText;
} finally
{
if (xmlDoc != null)
xmlDoc.Close();
}
}

Answer 2

关键代码在这里了
///节点遍历
while(xmlDoc.Read())
{
///节点的类型。xmlnode 类型就只有六类，元素，文本，文档类型，注释，处理指示，CDATA。
switch (xmlDoc.NodeType)
{
///是元素节点
case XmlNodeType.Element:nElements++;resultsArea.InnerText += "Element: " + xmlDoc.Name + " has " + xmlDoc.AttributeCount + " attributes\r\n";///获取节点属性数目
gnAttributes += xmlDoc.AttributeCount;
// 读取属性while (xmlDoc.MoveToNextAttribute())
{
resultsArea.InnerText += "\t" + xmlDoc.Name + "= " + xmlDoc.Value + "\r\n";
}
///终止case
break;

Membership.MinRequiredPasswordLength直接这样读

楼上的(第十维度)是MSDN的,不是我想要的

Answer 6

你是要用什么方式？
Membership会自己处理这些变配置属性。
Membership中都有相应的属性可以读出这些值
