T4模板从数据库模式为每个表创建*multiple*html(例如)输出文件

Question

我想使用一些T4模板来生成从sql server(在本例中)派生的数据库模式的html文件.对于数据库中的每个表,我想创建2个文件:

1. tableName_List.aspx - 将包含在asp.net GridView中显示的相应html,并为每个db表列定义一个网格列

2. tableName_Edit.aspx - 将包含在asp.net FormView中显示的相应html ,每个db表列都有一个文本框(为简单起见,现在)

所以,如果我在数据库中有5个表,我会得到10个文件输出.我一直在谷歌上搜索并找到相关文章,但大多数似乎都没有解决这个问题.我也看到了使用亚音速的参考,但我宁愿不再引入另一种技术.

下面的T4模板的代码将为您提供一个相对良好的开端.

您需要将相应版本的Microsoft.SqlSserver Smo DLL的引用添加到项目中.

需要在此代码中使用适合您环境的值替换以下项:

SERVERNAMEGOESHERE
DATABASENAMEGOESHERE
PROJECTNAMESPACEGOESHERE

<#@ template language="C#v3.5" hostspecific="true" #>
<#@ assembly name="System.Data" #>
<#@ assembly name="Microsoft.SqlServer.ConnectionInfo" #>
<#@ assembly name="Microsoft.SqlServer.Smo" #>
<#@ import namespace="System.Data.SqlClient" #>
<#@ import namespace="Microsoft.SqlServer.Management.Common" #>
<#@ import namespace="Microsoft.SqlServer.Management.Smo" #>
<#
    string connectionString = @"Server=SERVERNAMEGOESHERE;Trusted_Connection=True;";
    string databaseName = "DATABASENAMEGOESHERE";
    string projectNamespace = "PROJECTNAMESPACEGOESHERE";
    string relativeOutputFilePath = null;

    SqlConnection oneSqlConnection = new SqlConnection(connectionString);
    ServerConnection oneServerConnection = new ServerConnection(oneSqlConnection);
    Server oneServer = new Server(oneServerConnection);
    Database oneDatabase = oneServer.Databases[databaseName];
    foreach (Table oneTable in oneDatabase.Tables)
    {
        if (!oneTable.Name.Equals("sysdiagrams"))
        {

<asp:DataGrid ID="<#= oneTable.Name #>DataGrid" runat="server" AutoGenerateColumns="false">
    <Columns>
<#
            foreach (Column oneColumn in oneTable.Columns)
            {
#>
        <asp:BoundColumn DataField="<#= oneColumn.Name #>" HeaderText="<#= oneColumn.Name #>"></asp:BoundColumn>
<#
            }
#>
    </Columns>
</asp:DataGrid>
<#
            relativeOutputFilePath = @"\Output\" + oneTable.Name + "_List.aspx";
            TemplateHelper.WriteTemplateOutputToFile(relativeOutputFilePath, Host, GenerationEnvironment);
            GenerationEnvironment = new System.Text.StringBuilder();
#>

<#
            }
            relativeOutputFilePath = @"\Output\" + oneTable.Name + "_Edit.aspx";
            TemplateHelper.WriteTemplateOutputToFile(relativeOutputFilePath, Host, GenerationEnvironment);
            GenerationEnvironment = new System.Text.StringBuilder();
        }
    }

        string relativeOutputFilePath,

    {
        string outputPath = System.IO.Path.GetDirectoryName(Host.TemplateFile);
        string outputFilePath = outputPath + relativeOutputFilePath;
