bool ICollection<OperationParameterInfo>.Contains (System.Workflow.Activities.OperationParameterInfo item);
abstract member System.Collections.Generic.ICollection<System.Workflow.Activities.OperationParameterInfo>.Contains : System.Workflow.Activities.OperationParameterInfo -> bool
override this.System.Collections.Generic.ICollection<System.Workflow.Activities.OperationParameterInfo>.Contains : System.Workflow.Activities.OperationParameterInfo -> bool
Function Contains (item As OperationParameterInfo) As Boolean Implements ICollection(Of OperationParameterInfo).Contains
