-optioncompare
Specifies how string comparisons are made.
-optioncompare:{binary | text}
You can specify -optioncompare
in one of two forms: -optioncompare:binary
to use binary string comparisons, and -optioncompare:text
to use text string comparisons. By default, the compiler uses -optioncompare:binary
.
In Microsoft Windows, the current code page determines the binary sort order. A typical binary sort order is as follows:
A < B < E < Z < a < b < e < z < À < Ê < Ø < à < ê < ø
Text-based string comparisons are based on a case-insensitive text sort order determined by your system's locale. A typical text sort order is as follows:
(A = a) < (À = à) < (B=b) < (E=e) < (Ê = ê) < (Z=z) < (Ø = ø)
Have a project selected in Solution Explorer. On the Project menu, click Properties.
Click the Compile tab.
Modify the value in the Option Compare box.
The following code compiles ProjFile.vb
and uses binary string comparisons.
vbc -optioncompare:binary projFile.vb
