Declaration

public static string ToBasicStyleString(
    CriteriaOperator criteria,
    out OperandValue[] criteriaParametersList
)
Public Shared Function ToBasicStyleString(
    criteria As CriteriaOperator,
    ByRef criteriaParametersList As OperandValue()
) As String

Parameters

Type Name Description
CriteriaOperator criteria

A CriteriaOperator object that represents the expression to convert.

OperandValue[] criteriaParametersList

Receives the values that are marked by a question mark character in the result string.

Returns

Type Description
String

A string representation of the specified expression.

This example demonstrate how to use the ToBasicStyleString method:

OperandValue[] parameters;
CriteriaOperator filterCriteria = 
    CriteriaOperator.Parse("[Category] == ? && [Price] < ?", out parameters);

parameters[0].Value = "Saloon";
parameters[1].Value = 100000;

// Returns "[Category] = ? AND [Price] < ?"
string filterString = CriteriaOperator.ToBasicStyleString(filterCriteria, out parameters);

To convert the string representation of an expression to its CriteriaOperator equivalent, use the CriteriaOperator.Parse method.

Note

The ToBasicStyleString method returns a string representation of the criteria which can be displayed in a UI or saved in application log. However, this string is actually not SQL and cannot be considered as such.
