1、在Windows 2008 R2下安装telnet客户端PS C:\Users\Administrator> servermanagercmd -install telnet-client
2、使用XmlSerializer时移除xml声名和默认命名空间。
代码
protected string ToXml(object objectToConvert)
{
string str = null;
using (MemoryStream stream = new MemoryStream())
{
//XmlWriterSettings.OmitXmlDeclaration移除xml声明
using (XmlWriter xmlWriter = XmlTextWriter.Create(stream,
new XmlWriterSettings()
{ OmitXmlDeclaration = true, Encoding = Encoding.UTF8 }))
{
//移除命名空间
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");
XmlSerializer serializer = new XmlSerializer(objectToConvert.GetType());
serializer.Serialize(xmlWriter, objectToConvert, ns);
byte[] buffer = new byte;
stream.Position = 0;
stream.Read(buffer, 0, (int)stream.Length);
str = Encoding.UTF8.GetString(buffer);
xmlWriter.Close();
}
stream.Close();
}
if (str != null)
{
str = str.Trim();
}
return str;
}
3、WCF通信中如果出现序列化错误，如：
"对象图中可以序列化或反序列化的项目数目上限为“65536”"
请注意配置MaxItemsInObjectGraph。
#通过代码配置:
foreach (var op in client.Endpoint.Contract.Operations)
{
var dataContractBehavior = op.Behaviors
as DataContractSerializerOperationBehavior;
if (dataContractBehavior != null)
{
dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue;
}
}
#通过配置修改：
<dataContractSerializer maxItemsInObjectGraph="2147483647" />
4、IIS传输限制
<httpRuntime maxRequestLength="20000" executionTimeout="600" />
5、memcached Telnet Interface
