根据不同的需求，安装不同位数的 Rfc SDK
1.构造 Sap Adress Information，且继承 IDestinationConfiguration
public class SapAddressInfo : IDestinationConfiguration
{
public string SapHostIp { get; set; }
public string SapSystemNumber { get; set; }
public string SapUserAccount { get; set; }
public string SapUserPassword { get; set; }
public string SapClient { get; set; }
public string SapLanguage { get; set; }
public string SapPoolSize { get; set; }
public string SapPeakConnectionsLimit { get; set; }
public string SapConnectionIdleTimeout { get; set; }
public string DestinationName { get; set; }
RfcConfigParameters IDestinationConfiguration.GetParameters(string destinationName)
{
var parms = new RfcConfigParameters();
if (destinationName.Equals(DestinationName))
{
parms.Add(RfcConfigParameters.AppServerHost, SapHostIp); //SAP主机IP
parms.Add(RfcConfigParameters.SystemNumber, SapSystemNumber); //SAP实例
//通信账户 用户名 oms 密码123456
parms.Add(RfcConfigParameters.User, SapUserAccount); //用户名
parms.Add(RfcConfigParameters.Password, SapUserPassword); //密码
parms.Add(RfcConfigParameters.Client, SapClient); // Client
parms.Add(RfcConfigParameters.Language, SapLanguage); //登陆语言
parms.Add(RfcConfigParameters.PoolSize, SapPoolSize);
parms.Add(RfcConfigParameters.PeakConnectionsLimit, SapPeakConnectionsLimit);
parms.Add(RfcConfigParameters.ConnectionIdleTimeout, SapConnectionIdleTimeout);
}
return parms;
}
public bool ChangeEventsSupported()
{
return false;
}
event RfcDestinationManager.ConfigurationChangeHandler IDestinationConfiguration.ConfigurationChanged
{
// ReSharper disable once ValueParameterNotUsed
add { }
// ReSharper disable once ValueParameterNotUsed
remove { }
}
}
2.创建一个Sap连接的服务接口
public interface ISapConnection
{
RfcDestination Destination { get; set; }
void Open();
void Dispose();
}
3.接下来我们对接口进行实现
public class SapConnection : IDisposable, ISapConnection
{
private const string SapHostIpName = "SapHostIpName";
private const string SapSystemNumberName = "SapSystemNumberName";
private const string SapUserAccountName = "SapUserAccountName";
private const string SapUserPasswordName = "SapUserPasswordName";
private const string SapClientName = "SapClientName";
private const string SapLanguageLanguage = "SapLanguageLanguage";
private const string SapPoolSizeName = "SapPoolSizeName";
private const string SapPeakConnectionsLimitName = "SapPeakConnectionsLimitName";
private const string SapConnectionIdleTimeoutName = "SapConnectionIdleTimeoutName";
private const string DestinationName = "DestinationName";
public SapConnection(Object settingsManager)
{
if (settingsManager == null)
throw new ArgumentNullException(nameof(settingsManager));
//自行赋值
var sapHostIp = "SapHostIpName";
var sapSystemNumber = "SapSystemNumberName";
var sapUserAccount = "SapUserAccountName";
var sapUserPassword = "SapUserPasswordName";
var sapClient = "SapClientName";
var sapLanguage = "SapLanguageLanguage";
var sapPoolSize = "SapPoolSizeName";
var sapPeakConnectionsLimit = "SapPeakConnectionsLimitName";
var sapConnectionIdleTimeout = "SapConnectionIdleTimeoutName";
var destinationName = "DestinationName";
SapAddressInfo = new SapAddressInfo
{
SapHostIp = sapHostIp,
SapSystemNumber = sapSystemNumber,
SapUserAccount = sapUserAccount,
SapUserPassword = sapUserPassword,
SapClient = sapClient,
SapLanguage = sapLanguage,
SapPoolSize = sapPoolSize,
SapPeakConnectionsLimit = sapPeakConnectionsLimit,
SapConnectionIdleTimeout = sapConnectionIdleTimeout,
DestinationName = destinationName/*"ECQ"*/
};
if (!RfcDestinationManager.IsDestinationConfigurationRegistered())
{
RfcDestinationManager.RegisterDestinationConfiguration(SapAddressInfo);
}
}
public SapAddressInfo SapAddressInfo { get; set; }
public RfcDestination Destination { get; set; }
public void Open()
{
try
{
Destination = RfcDestinationManager.TryGetDestination(SapAddressInfo.DestinationName);
if (Destination == null)
{
if (!RfcDestinationManager.IsDestinationConfigurationRegistered())
{
RfcDestinationManager.RegisterDestinationConfiguration(SapAddressInfo);
}
Destination = RfcDestinationManager.GetDestination(SapAddressInfo.DestinationName);
}
}
catch (Exception ex)
{
throw new Exception("An exception occurred when trying to open a SapConnection. Check inner exception for details.", ex);
}
}
public void Dispose()
{
//RfcDestinationManager.UnregisterDestinationConfiguration(SapAddressInfo);
if (SapAddressInfo != null)
{
try
{
RfcDestinationManager.UnregisterDestinationConfiguration(SapAddressInfo);
}
catch (Exception ex)
{
Trace.TraceError("An error occurred when trying to unregister destination configuration. Exception: {0}", ex);
}
}
GC.SuppressFinalize(this);
}
}
4.这样你就可以使用这个接口进行连接了
using (var SapConnection = new SapConnection(_settingsManager))
{
SapConnection.Open();
var function = SapConnection.Destination.Repository.CreateFunction("fucntion");
if (param != null)
{
var inputTable = function.GetTable("123");
inputTable.Append();
inputTable.SetValue("11", param.Sign);
inputTable.SetValue("22", param.Option);
inputTable.SetValue("33", param.Low);
inputTable.SetValue("44", param.High);
}
function.Invoke(SapConnection.Destination);
var result = function.GetTable("return");
//解析
}
如果是用Bapi 提交数据，需要加Session最稳妥，可以保证数据提交成功，查询就无所谓了。
