System.Object Methods

LINQ to SQL supports the following Object methods:

• Object.Equals(Object)
• Object.Equals(Object, Object)
• Object.ToString()

LINQ to SQL does not support the following Object methods:

• Object.GetHashCode()
• Object.ReferenceEquals(Object, Object)
• Object.MemberwiseClone()
• Object.GetType()
• Object.ToString() for binary types such as BINARY, VARBINARY, IMAGE, and TIMESTAMP.

Differences from .NET

The output of Object.ToString() for double uses SQL CONVERT(NVARCHAR(30), @x, 2) on SQL. SQL always uses 16 digits and scientific notation in this case (for example, "0.000000000000000e+000" for 0). As a result, Object.ToString() conversion does not produce the same string as Convert.ToString in the .NET Framework.
