-optioncompare
Specifies how string comparisons are made.
Syntax
-optioncompare:{binary | text}
Remarks
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)
To set -optioncompare in the Visual Studio IDE
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.
To set -optioncompare programmatically
Example
The following code compiles ProjFile.vb
and uses binary string comparisons.
vbc -optioncompare:binary projFile.vb
