<Variablename>' will not be inferred because it is a static local variable

  • Artikel

The compiler does not infer the data type of static local variables. In the following example, with Option Strict set to Off, the type of m will be Object, regardless of whether Option Infer is set to On or Off. Local type inference does not apply.

Sub Main()
    Static m = 10
End Sub

By default, this message is a warning. For information about how to hide warnings or how to treat warnings as errors, see Configuring Warnings in Visual Basic.

Error ID: BC42111

To address this warning

  • Specify the data type for static local variables.

    For example, if you want m in the previous example to be of type Integer, specify the type in the declaration.

    Sub Main()
    Static m As Integer = 10
End Sub
