关于在C#中解析XML字符串的问题.

[skming美女相册]

调用了一个外部 的servlet返回来一个字符串数组,字符串里的内容是XML格式的 byte[] byRemoteInfo

<row><loginname>chentianya</loginname><loginpwd>25d55ad283aa400af464c76d713c07ad</loginpwd><username>%E7%9C%81%E5%8F%91%E6%94%B9%E5%A7%94%E7%94%B5%E5%AD%90%E7%9B%91%E5%AF%9F%E7%94%A8%E6%88%B7</username><email>0</email><mobile>0</mobile><parentid>ff80808116e773020116eb07e91a0044</parentid><othertype>0</othertype><usersort>1</usersort></row>

我现在想把byte[] byRemoteInfo里的东西按照接点一条条读到相应的变量里.
找了很多都是从外部读XML文件的代码和例子可是我这里已经读到字符串里了呀.
请大家帮忙.

确实只要LoadXml就可以，不过只完成了第一步，楼主的意思是还要取得每个结点的值读到变量里：
简单点（方法中的代码如下）：
string strTemp = "<row><loginname> chentianya </loginname> <loginpwd> 25d55ad283aa400af464c76d713c07ad </loginpwd> <username> %E7%9C%81%E5%8F%91%E6%94%B9%E5%A7%94%E7%94%B5%E5%AD%90%E7%9B%91%E5%AF%9F%E7%94%A8%E6%88%B7 </username> <email> 0 </email> <mobile> 0 </mobile> <parentid> ff80808116e773020116eb07e91a0044 </parentid> <othertype> 0 </othertype> <usersort> 1 </usersort> </row>";
string strLoginName=string.Empty;
string strLoginPassword = string.Empty;
string strUserName = string.Empty;
string strEmail = string.Empty;
string strMobile = string.Empty;
string strParentId = string.Empty;
string strOtherType = string.Empty;
string strUserSort = string.Empty;

XmlDocument xd = new XmlDocument();
xd.LoadXml(strTemp.Trim());
XmlNode xnRoot = xd.SelectSingleNode("row");
if (xnRoot != null)
{
strLoginName = xnRoot.ChildNodes[0].InnerText.ToString();
strLoginPassword = xnRoot.ChildNodes[1].InnerText.ToString();
strUserName=xnRoot.ChildNodes[2].InnerText.ToString();
strEmail=xnRoot.ChildNodes[3].InnerText.ToString();
strMobile=xnRoot.ChildNodes[4].InnerText.ToString();
strParentId=xnRoot.ChildNodes[5].InnerText.ToString();
strOtherType=xnRoot.ChildNodes[6].InnerText.ToString();
strUserSort = xnRoot.ChildNodes[7].InnerText.ToString();
}

居然结贴了。。。这么快

C#中byte[]与string的转换
1、
System.Text.UnicodeEncoding converter = new System.Text.UnicodeEncoding();
byte[] inputBytes =converter.GetBytes(inputString);
string inputString = converter.GetString(inputBytes);
2、
string inputString = System.Convert.ToBase64String(inputBytes);
byte[] inputBytes = System.Convert.FromBase64String(inputString);


1、
System.Text.UnicodeEncoding converter = new System.Text.UnicodeEncoding();
byte[] inputBytes =converter.GetBytes(inputString);
string inputString = converter.GetString(inputBytes);
2、
string inputString = System.Convert.ToBase64String(inputBytes);
byte[] inputBytes = System.Convert.FromBase64String(inputString);

[我自横刀香甜笑]

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);
str就是你转成的字符串。

我发现自己真的很无聊～～

^_^LS何出此言呢,写的不错呢

2楼的，LoadXml就可以了
