'System.Configuration.ConfigurationSettings.Ap

Question

I got the following warning

'System.Configuration.ConfigurationSettings.AppSettings' is obsolete: '"This method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings"'

How do you fix it?

Answer 1

to use ConfigurationManager.AppSettings[""] Add Reference Assemblies not use using System.Configuration;

Answer 2

you must add reference of System.onfiguration in your project then add "Using System.onfiguration;"

next step using like this:

private string SQLConnectionString = ConfigurationManager.AppSettings["SQlConnectionString"]; 

Answer 3

Add a reference to the assembly System.Configuration.

Then at the top (assuming C#) using System.Configuration (Imports System.Configuration in VB.NET).

Use ConfigurationManager.AppSettings["MySetting"] to access the settings!

Answer 4

I had the same problem in a C# project and I fixed it by writing appSettings instead of AppSettings in the XML file (camelCase expected) in the tag

<appSettings>
  <add key="myKey" value="my Value"/>
<appSettings>

After all C# is case sensitive

Answer 5

example:

replace

string smtpServer = System.Configuration.ConfigurationSettings.AppSettings["EmailServer"];

with

string smtpServer = ConfigurationManager.AppSettings["EmailServer"];

also make sure on the top of the case you add:

using System.Configuration;

Answer 6

Just replace
System.Configuration.ConfigurationSettings.AppSettings
with
System.Configuration!System.Configuration.ConfigurationManager.AppSettings
in your code.
