If you are not using the text files from How to write to a text file , replace the argument to ReadAllText and ReadAllLines with the appropriate path and file name on your computer.
Do not rely on the name of a file to determine the contents of the file. For example, the file myFile. Skip to main content. They make it easier to use lambda expressions without declaring a variable of a delegate type, and they work more seamlessly with the new ASP. In C 10, const strings may be initialized using string interpolation if all the placeholders are themselves constant strings.
String interpolation can create more readable constant strings as you build constant strings used in your application. The placeholder expressions can't be numeric constants because those constants are converted to strings at run time.
The current culture may affect their string representation. Learn more in the language reference on const expressions. In C 10, you can add the sealed modifier when you override ToString in a record type. Sealing the ToString method prevents the compiler from synthesizing a ToString method for any derived record types.
A sealed ToString ensures all derived record types use the ToString method defined in a common base record type. You can learn more about this feature in the article on records. This change removes a restriction from earlier versions of C. Previously, a deconstruction could assign all values to existing variables, or initialize newly declared variables:. Prior to C 10, there were many scenarios where definite assignment and null-state analysis produced warnings that were false positives.
These generally involved comparisons to boolean constants, accessing a variable only in the true or false statements in an if statement, and null coalescing expressions. These examples generated warnings in previous versions of C , but don't in C The main impact of this improvement is that the warnings for definite assignment and null-state analysis are more accurate.

So the external app will attempt to use my URL as the file name. Which will usually be some sort of id for the document in the database, typically with out a file extension.
This makes for a pretty poor the name does not match the URL used to access the file, for the scenario is that if you don't provide. Using the Inline property on the Content-Disposition allows me to separate the ability of setting the file name from the behavior of forcing the download or not. Just an addition: Response.

Serj Sagan Serj Sagan Not recommended, Content-Disposition is the prefered method for clarity and compatability.
Thanks for that. Lying about the content type sounds like a really bad idea. Some browsers depend on correct content type to suggest applications for the user in the "save-or-open" dialog. If your intent is to have the browser suggest an app then that's fine, but this question is specifically about forcing the download Didn't try with e.
