The right.
Returns
System.Boolean

Boolean result.
Overrides

CompareStringExpressions(StringExpression, StringExpression)

Compares two string expressions for equality using case-insensitive comparison.

Declaration
protected override bool CompareStringExpressions(StringExpression left, StringExpression right)
Parameters
