我有以下代码
public bool StartWCF()
{
try
{
// Select the first entry. I hope it's this maschines IP
// IPAddress _ipAddress = ips.AddressList[0];
var ipAddress = new IPAddress(new byte[] { 127, 0, 0, 1 });
// Create the url that is needed to specify where the service should be started
this.m_UrlMetaServiceComm = "net.tcp://" + ipAddress + ":8000/VSMDBCommunication";
this.m_UrlMetaServicePart = "net.tcp://" + ipAddress + ":8000/VSMDBPartType";
string endPointAddrComm = this.m_UrlMetaServiceComm;
var tcpBindingComm = new NetTcpBinding
{
TransactionFlow = false,
MaxReceivedMessageSize = 20000000,
MaxBufferSize = 20000000,
MaxBufferPoolSize = 20000000,
ReaderQuotas = { MaxNameTableCharCount = 20000000 },
OpenTimeout = new TimeSpan(0, 5, 0),
SendTimeout = new TimeSpan(0, 5, 0),
CloseTimeout = new TimeSpan(0, 5, 0)
};
tcpBindingComm.Security.Transport.ProtectionLevel = ProtectionLevel.EncryptAndSign;
tcpBindingComm.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;
tcpBindingComm.Security.Mode = SecurityMode.None;
var endpointAddressComm = new EndpointAddress(endPointAddrComm);
this.m_ChannelCommunication = ChannelFactory<IVSMDBCommunication>.CreateChannel(
tcpBindingComm, endpointAddressComm);
((IContextChannel)m_ChannelCommunication).OperationTimeout = new TimeSpan(0, 5, 0);
string endPointAddrPart = this.m_UrlMetaServicePart;
var tcpBindingPart = new NetTcpBinding
{
TransactionFlow = false,
MaxReceivedMessageSize = 20000000,
MaxBufferSize = 20000000,

}
当底层进程花费超过一分钟时,我偶尔会遇到以下错误。
消息:
此请求操作发送到 的net.tcp://127.0.0.1:8000 / VSMDBCommunication 没有得到回复 配置超时(00:01:00)。该 分配给此操作的时间可能 是一段时间的一部分 超时。这可能是因为 服务仍在处理中 操作或因为服务 无法发送回复消息。 请考虑增加 操作超时(通过强制转换 通道/代理到IContextChannel和 设置OperationTimeout属性) 并确保服务能够 连接到客户端。
如何以不同于我正在做的方式转换频道以避免此错误,这是有道理的,因为基础请求可能需要稍微超过一分钟来计算。

将客户端操作时间设置为
client.InnerChannel.OperationTimeout = TimeSpan.FromMinutes(10);
这将删除您的错误。

尝试设置ReceiveTimeout属性。
