ArcGIS Pro 2.7 API Reference Guide
EnvelopeBuilder Constructor(Double,Double,Double,Double,SpatialReference)
Example 

ArcGIS.Core.Geometry Namespace > EnvelopeBuilder Class > EnvelopeBuilder Constructor : EnvelopeBuilder Constructor(Double,Double,Double,Double,SpatialReference)
Lower left corner x value of the envelope.
Upper right corner y value of the envelope.
Lower left corner x value of the envelope.
Upper right corner y value of the envelope.
(Optional) The SpatialReference. The default value is null.
Initializes a new instance of the EnvelopeBuilder class. This method must be called on the MCT. Use QueuedTask.Run
Syntax
Public Function New( _
   ByVal xMin As Double, _
   ByVal yMin As Double, _
   ByVal xMax As Double, _
   ByVal yMax As Double, _
   Optional ByVal spatialReference As SpatialReference _
)

Parameters

xMin
Lower left corner x value of the envelope.
yMin
Upper right corner y value of the envelope.
xMax
Lower left corner x value of the envelope.
yMax
Upper right corner y value of the envelope.
spatialReference
(Optional) The SpatialReference. The default value is null.
Exceptions
ExceptionDescription
This method or property must be called within the lambda passed to QueuedTask.Run.
Remarks
The resulting envelope is normalized to ensure its XMin <= XMax and YMin <= YMax. If any of the input values are NaN, then the envelope is set to empty.
Example
// Use a builder convenience method or use a builder constructor.

// Builder convenience methods don't need to run on the MCT.
Envelope envelope = EnvelopeBuilder.CreateEnvelope(100.0, 100.0, 500.0, 500.0);

// shrink the envelope by 50%
Envelope result = envelope.Expand(0.5, 0.5, true);

// Builder constructors need to run on the MCT.
ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
{
  using (EnvelopeBuilder eBuilder = new EnvelopeBuilder(100.0, 100.0, 500.0, 500.0))
  {
    // shrink by 50%
    eBuilder.Expand(0.5, 0.5, true);

    result = eBuilder.ToGeometry();
  }
});

// builderEx constructors don't need to run on the MCT.
EnvelopeBuilderEx builderEx = new EnvelopeBuilderEx(100.0, 100.0, 500.0, 500.0);
builderEx.Expand(0.5, 0.5, true);
envelope = builderEx.ToGeometry() as Envelope;
