How to detect if var is a string

I am having a bit of trouble using an if statement to detect if my numericupdown object is a string so I don't use a decimal variable to adjust it. I saw there was a type of commmand, but I am having trouble using it. Here is what I am looking at:

if(typeof sentNUD.Value == string)
{
       //Do string arguments here
}
else
{
        //do decimal arguments here
}

The syntax of the if statement is wrong though and I get an error. How do I set up that if statement correctly? I tried looking around a bit, but I am having trouble understanding how to do this correctly. Thank you.

Should you use the method's static overloading to work your solution ??

The use of "typeOf" is normaly frowned by OO purists.

You can use the "is"-operator:

if(variable is string)
{

}

if (sentNUD.Value.GetType() == typeof(string))
{
// string stuff
}
