概观

为了方便起见，这里的大多数演示使用的数据集将作为数据源。因为在.NET 2.0中不支持Linq，如果我们使用Linq，这些演示将不适用于所有人，而且焦点在Excel模板中，而不是在数据层中。但是您可以将任何IQueryable< T >集合用作FlexCel报表中的数据源，这是我们将在此处显示的内容。

所示概念

当详细信息嵌套在主服务器内的多个级别时，如何执行master-detail报表。

• 在这种情况下，Country类具有People类，People类具有Language对象列表。如果People是Country里面的List < >且你想使用该列表，你只需要定义一个__People__带（这将在Linq示例中显示）。但是由于List < >在People内，而People又在Country内，因此你需要定义一个__People.Language__ band。

如何使用[square brackets]引用带点的表格。

• 如果你写一个单元格< #tablename.section.field> FlexCel将此解释为表“tablename”，字段“section.field”。直到第一个点的文本始终是表，其余的是字段。
• 有时您可能希望将其解释为表“tablename.section”，字段“field”。为此，您需要编写<  #[tablename.section].field>。在这种特殊情况下，我们有一个表“People.Language”，在前一点中定义了它。如果我们在单元格B1中写道：“< #people.language.speakers.percen>FlexCel会解释这是表“people”，而不是“people.language”，这就是我们需要的。让FlexCel明白我们想要一张表< #[people.language] .speakers.percent>

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
//
[assembly: AssemblyTitle("")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Revision and Build Numbers 
// by using the '*' as shown below:
[assembly: AssemblyVersion("6.26.0.0")]
//
// In order to sign your assembly you must specify a key to use. Refer to the 
// Microsoft .NET Framework documentation for more information on assembly signing.
//
// Use the attributes below to control which key is used for signing. 
//
// Notes: 
//   (*) If no key is specified, the assembly is not signed.
//   (*) KeyName refers to a key that has been installed in the Crypto Service
//       Provider (CSP) on your machine. KeyFile refers to a file which contains
//       a key.
//   (*) If the KeyFile and the KeyName values are both specified, the 
//       following processing occurs:
//       (1) If the KeyName can be found in the CSP, that key is used.
//       (2) If the KeyName does not exist and the KeyFile does exist, the key 
//           in the KeyFile is installed into the CSP and used.
//   (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
//       When specifying the KeyFile, the location of the KeyFile should be
//       relative to the project output directory which is
//       %Project Directory%\obj\. For example, if your KeyFile is
//       located in the project directory, you would specify the AssemblyKeyFile 
//       attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
//   (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
