泛型约束可以使用在方法中吗?
public abstract class DataAccess<TDataTable, TDataContext> : IDisposable
where TDataTable : class, new()
where TDataContext : DataContext, new()
{
}

///如何在某个方法中使用?

public abstract class DataAccess {
public void NewData<TDataTable, TDataContext>()
where TDataTable : class, new()
where TDataContext : DataContext, new()
{}
}

[解决办法]
可以，类似的

C# code

public static void OpTest<T>(T s, T t) where T : class{    System.Console.WriteLine(s == t);}static void Main(){    string s1 = "foo";    System.Text.StringBuilder sb = new System.Text.StringBuilder("foo");    string s2 = sb.ToString();    OpTest<string>(s1, s2);}
