我第一次使用 T4 开发实用程序来生成 .aspx、.aspx.cs 文件以及存储过程。为此,我需要将一些参数(如表名、页面名等)从 Windows 窗体传递到 T4 模板。我已经编写了模板和一个 customHost 作为给定 http://msdn.microsoft.com/en-us/library/bb126579.aspx从窗口窗体调用。现在我可以从 Windows 窗体调用 T4 模板,但我不知道如何将参数传递给 T4 模板。我试图在模板中创建属性并从 Win 表单调用模板,但它在“var sessionHost = (ITextTemplatingSessionHost) this.Host;”这一行给我错误因为我使用 CustomHost。请帮帮我。
这是 T4 模板的代码示例
Text Template Host Test
<#@ template debug="true" #>
<#@ parameter name="MyParameter" type="System.String" #>
<# for (int i=0; i<3; i++)
{
WriteLine("This is a test");
}
#>
Parameter in statement block: <# Write(MyParameter); #>

我已尝试但出现错误“无法将类型为‘FormGenerator.CustomHost’的对象转换为类型为‘Microsoft.VisualStudio.TextTemplating.ITextTemplatingSessionHost’。”
CustomHost Host = new CustomHost();

string templateFile = Host.ResolvePath("TestTemplate.tt");
string templateContent = File.ReadAllText(templateFile);
TextTemplatingSession session = new TextTemplatingSession();
session["MyParameter"] = "SessionValue";
var sessionHost = (ITextTemplatingSessionHost)Host;
sessionHost.Session = session;
Engine engine = new Engine();
string generatedContent = engine.ProcessTemplate(templateContent, Host);
请帮我看看我该如何解决这个问题。提前致谢。

您需要使您的 CustomHos 类可序列化
[Serializable()]
class CustomCmdLineHost : ITextTemplatingEngineHost
