运行 ASP.NET 应用程序时出现 CS0102 错误

Question

I get this error in the App_directory C# code file,

CS0102: The type ClassName already contains a definition for 'mappingSource'

It points to line,

private static System.Data.Linq.Mapping.MappingSource mappingSource = new AttributeMappingSource();

What is the likely mistake? Using vs 2008 and .net 3.5

Answer 1

It means the class 'ClassName' already has a 'member' (aka variable) named 'mappingSource' defined. So just choose another name for it and it should compile.
