Workaround for String.Contains() in C# .NetCF 2.0?

Question

There is a string method called Contains. It allows you to quickly search a string for another string. I need to use this in a .netcf 2.0 application but per MSDN it does not come available until the 3.5 framework.

Can anyone offer a work around (C#)?

TIA Noble

Answer 1

You could try using String.IndexOf . If it returns -1, the string does not exist inside the other string.

Answer 2

那么string.IndexOf ，只是检查它是否返回大于-1？

Answer 3

Browsing " String.Contains " in Reflector gives below. I think this can be used directly in code.

Public Function Contains(ByVal value As String) As Boolean
    Return (Me.IndexOf(value, StringComparison.Ordinal) >= 0)
End Function

Also a C# version

public bool Contains(string value)
{
    return (this.IndexOf(value, StringComparison.Ordinal) >= 0);
}
