Dataset/datatable is a value type or reference type

Question

Is datatable/dataset is value type of reference type?

But the most important question in my mind is- "how to find whether a type is a value type or reference type?"

Answer 1

They are both reference types.

You can look up the information on MSDN - if they are classes, they are reference types, if structs, value types.

See DataTable and DataSet. As you can see, they are both declared as classes.

Answer 2

You can use the Type.IsValueType method.

Answer 3

Both are reference type

DataTable dt = new  DataTable();

Type t = dt.GetType();

bool isValueType  = t.IsValueType;

isValueType will return false.
