+# \<typeparamref> (Visual Basic)
+
+Formats a word as a type parameter.  
+  
+## Syntax  
+  
+```xml  
+<typeparamref name="name"/>  
+```  
+  
+## Parameters  
+
+ `name`  
+ The name of the type parameter to refer to. Enclose the name in double quotation marks (" ").  
+  
+## Remarks  
+
+ The `<typeparamref>` tag gives you a way to indicate that a word is a type parameter. The XML file can be processed to format this type parameter in some distinct way, for example in italics.  
+  
+ Compile with [-doc](../../reference/command-line-compiler/doc.md) to process documentation comments to a file.  
+  
+## Example  
+
+ This example uses the `<typeparamref>` tag to refer to the `T` type parameter.
