Removing extranious data from a string @{Name=WEBHOST001-OI3w}

If I had more information I might be able to help.

Is that string the output of another command or object?
Is that string coming from Restful API queries?

The reason I ask is a lot of times you see that output surrounded by the at symbol and curly braces when a property value contains another "child object". In those cases when you find out the Properties name you can simply pipe it to. . .

Select-Object -ExpandProperty <insert property name>

Tell us how to get this output ourselves so we can reproduce it and help you extract the string you were hoping to get.
