Specify Attribute Value Length

Introduction

Welcome to the world of Aspose.GIS for .NET – your gateway to powerful and efficient geospatial development! This comprehensive tutorial will guide you through the fundamental steps of using Aspose.GIS to manage geospatial data effortlessly in your .NET applications. Whether you’re a seasoned developer or a newcomer to geospatial programming, this guide is designed to provide you with a solid foundation and practical insights.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites in place:

  • Aspose.GIS for .NET Library: Download and install the Aspose.GIS for .NET library from the download link.
  • Development Environment: Set up your preferred .NET development environment, such as Visual Studio.
  • Document Directory: Specify the directory where your geospatial documents will be stored.

Import Namespaces

using Aspose.Gis;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

Create VectorLayer

Start by creating a VectorLayer, a fundamental component for working with geospatial data.

string dataDir = "Your Document Directory";
using (VectorLayer layer = VectorLayer.Create(dataDir + "SpecifyAttributeValueLength_out.shp", Drivers.Shapefile))
{
    // Your code for the next steps will go here.
}

Add Attribute with Specific Length

Before adding features, define an attribute with a specified length.

FeatureAttribute attribute = new FeatureAttribute("wide", AttributeDataType.String);
attribute.Width = 120;
layer.Attributes.Add(attribute);

Construct and Add Feature

Construct a feature and set its attribute value within the specified length.

Feature feature = layer.ConstructFeature();
feature.SetValue("wide", "this string can be up to 120 characters long now.");
layer.Add(feature);

Congratulations! You’ve successfully specified the attribute value length using Aspose.GIS for .NET.
