将vb.net转换为C＃：一行代码

Question

This link offers sample code to infer the schema of an XML file, in VB.NET. One particular line fails in my translation to C#, namely,

Dim schema As XmlSchema = schemaSet.Schemas()(0)

My translation is

XmlSchema schema = schemaSet.Schemas()[0];

I cannot see what is wrong with my translation?

Answer 1

XmlSchemaSet.Schemas() returns an ICollection which you can't access by index. If you use use .NET 3.5 you can use Linq to do:

schemaSet.Schemas().Cast<XmlSchema>().First();

Otherwise you have to use a foreach loop and stop after the first iteration.
