Using the ConditionExpression Class

[Applies to: Microsoft Dynamics CRM 4.0]

The ConditionExpression class is used to compare an attribute to a value or set of values by using an operator such as equal, greater than, or like.

The following table lists the properties that you set to create a condition by using the ConditionExpression class.

When you create a condition that compares an attribute value to an enumeration such as a state code, you must use the ToString method to convert the value to a string.

Example

The following code example shows how to use the ConditionExpression class.

// Create the ConditionExpression.
ConditionExpression condition = new ConditionExpression();

// Set the condition to be when the account owner's last name is not Cannon.
condition.AttributeName = "lastname";
condition.Operator = ConditionOperator.Equal;
condition.Values = new string [] {"Cannon"};

The following code example shows how to use the ConditionExpression class to test for the inactive state.

ConditionExpression ce = new ConditionExpression();
ce.AttributeName = "statecode";
ce.Operator = ConditionOperator.Equal;
ce.Values = new object[]{AccountState.Inactive.ToString()};
