-----------------------------
Key: DNET-546
URL: http://tracker.firebirdsql.org/browse/DNET-546
Project: .NET Data provider
Issue Type: Improvement
Components: ADO.NET Provider
Affects Versions: 4.1.0.0
Environment: Visual Studio 2012, .NET 4.0
Reporter: Gabor Lakatos
Assignee: Jiri Cincura
Priority: Minor
I have new extension form FbDataReader class. I extend Get... (GetString,
GetInt32, etc) methods for new parameters. Example: GetString("FIELDNAME",
"DefaultValue").
The code:
using System;
using FirebirdSql.Data.FirebirdClient;
public static class FbDataReaderEx
{
public static bool GetBoolean(this FbDataReader oR, string FieldName, bool
Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetBoolean(oR.GetOrdinal(FieldName));
}
}
public static byte GetByte(this FbDataReader oR, string FieldName, byte
Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetByte(oR.GetOrdinal(FieldName));
}
}
public static DateTime GetDateTime(this FbDataReader oR, string FieldName,
DateTime Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetDateTime(oR.GetOrdinal(FieldName));
}
}
public static decimal GetDecimal(this FbDataReader oR, string FieldName,
decimal Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetDecimal(oR.GetOrdinal(FieldName));
}
}
public static double GetDouble(this FbDataReader oR, string FieldName,
double Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetDouble(oR.GetOrdinal(FieldName));
}
}
public static Type GetFieldType(this FbDataReader oR, string FieldName)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return null;
}
else
{
return oR.GetFieldType(oR.GetOrdinal(FieldName));
}
}
public static float GetFloat(this FbDataReader oR, string FieldName, float
Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetFloat(oR.GetOrdinal(FieldName));
}
}
public static Guid GetGuid(this FbDataReader oR, string FieldName, Guid
Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetGuid(oR.GetOrdinal(FieldName));
}
}
public static Int16 GetInt16(this FbDataReader oR, string FieldName, Int16
Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetInt16(oR.GetOrdinal(FieldName));
}
}
public static Int32 GetInt32(this FbDataReader oR, string FieldName, Int32
Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetInt32(oR.GetOrdinal(FieldName));
}
}
public static Int64 GetInt64(this FbDataReader oR, string FieldName, Int64
Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetInt64(oR.GetOrdinal(FieldName));
}
}
public static string GetString(this FbDataReader oR, string FieldName,
string Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetString(oR.GetOrdinal(FieldName));
}
}
public static object GetValue(this FbDataReader oR, string FieldName,
object Default)
{
if (oR.IsDBNull(oR.GetOrdinal(FieldName)))
{
return Default;
}
else
{
return oR.GetValue(oR.GetOrdinal(FieldName));
}
}
public static bool IsDBNull(this FbDataReader oR, string FieldName)
{
return oR.IsDBNull(oR.GetOrdinal(FieldName));
}
}
I would be happy if the new procedures would appear in the new version.
Thanks,
Gabor
