using statement with multiple variables [duplicate]

Question

This question already has an answer here:

• Nested using statements in C# 16 answers

Is it possible to make this code a little more compact by somehow declaring the 2 variable inside the same using block?

using (var sr = new StringReader(content))
{
    using (var xtr = new XmlTextReader(sr))
    {
        obj = XmlSerializer.Deserialize(xtr) as TModel;
    }
}

Answer 1

The accepted way is just to chain the statements:

using (var sr = new StringReader(content))
using (var xtr = new XmlTextReader(sr))
{
    obj = XmlSerializer.Deserialize(xtr) as TModel;
}

Note that the IDE will also support this indentation, i.e. it intentionally won’t try to indent the second using statement.

Answer 2

The following only works for instances of the same type! Thanks for the comments.

This sample code is from MSDN:

using (Font font3 = new Font("Arial", 10.0f), font4 = new Font("Arial", 10.0f))
{
    // Use font3 and font4.
}
