[英]How to Load Xml file whilelocking it using XDocument.Load() method?
[英]Load a xml file using XDocument.Load from FileSystemWatcher. Error “The process cannot access the file..etc”
有沒有辦法糾正錯誤“該進程無法訪問該文件.etc”。 流程是,當我檢測到我需要從xml文件讀取特定節點的xml文件時,filesystemwatcher將監視xml文件。
我怎樣才能解決這個問題? 任何想法或建議都會有很大幫助。 謝謝
這是filesystemwatcher代碼
private void fileSystemWatcher_Created(object sender, System.IO.FileSystemEventArgs e)
{
try
{
string type = GetType(e.FullPath).ToUpper();
if (type == "CC")
{
if (Global.pc_flag)
{
ProcessPC(e.FullPath);
}
else if (Global.mw_flag)
{
ProcessMW(e.FullPath);
}
else
{
ProcessXML(e.FullPath);
}
}
else if (type == "GC")
{
ProcessMW(e.FullPath);
}
//Process(e.FullPath);
}
catch(Exception ex)
{
error++;
lblErrors.Text = error.ToString();
MessageBox.Show(ex.Message);
}
}
此處包含GetType
private string GetType(string file)
{
string type = string.Empty;
using (var stream = File.Open(file, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
var request = XDocument.Load(stream);
var get_command = from r in request.Descendants("Transaction")
select new
{
Type = r.Element("Type").Value
};
foreach (var c in get_command)
{
type = c.Type;
}
}
return type;
}
您不會在代碼中使用stream
,並且在流打開時無法訪問XDocument.Load(file)
private string GetType(string file)
{
string type = string.Empty;
var request = XDocument.Load(file);
var get_command = from r in request.Descendants("Transaction")
select new
{
Type = r.Element("Type").Value
};
foreach (var c in get_command)
{
type = c.Type;
}
return type;
}
