The following example creates a Project object and uses the LoadXml method to add content to the project. The BuildProperty, BuildPropertyGroup, and BuildPropertyGroupCollection classes are used to add, remove, and change items in the project.
using System; using System.Collections.Generic; using System.Text; using Microsoft.Build.BuildEngine; namespace AddNewProperty { class Program { /// <summary> /// This code demonstrates the use of the following methods: /// Engine constructor /// Project constructor /// Project.LoadFromXml /// Project.Xml /// BuildPropertyGroupCollection.GetEnumerator /// BuildPropertyGroup.GetEnumerator /// BuildProperty.Name (get) /// BuildProperty.Value (set) /// BuildPropertyGroup.RemoveProperty /// BuildPropertyGroup.AddNewProperty /// </summary> static void Main() { // Create a new Engine object. Engine engine = new Engine(Environment.CurrentDirectory); // Create a new Project object. Project project = new Project(engine); // Load the project with the following XML, which contains // two PropertyGroups. project.LoadXml(@" <Project xmlns='http://schemas.microsoft.com/developer/msbuild/2003'> <PropertyGroup> <Optimize>true</Optimize> <WarningLevel>4</WarningLevel> </PropertyGroup> <PropertyGroup> <OutputPath>bin\debug\</OutputPath> <RemoveThisPropertyPlease>1</RemoveThisPropertyPlease> </PropertyGroup> </Project> "); // Iterate through each PropertyGroup in the Project. There are two. foreach (BuildPropertyGroup pg in project.PropertyGroups) { BuildProperty propertyToRemove = null; // Iterate through each Property in the PropertyGroup. foreach (BuildProperty property in pg) { // If the property's name is "RemoveThisPropertyPlease", then // store a reference to this property in a local variable, // so we can remove it later. if (property.Name == "RemoveThisPropertyPlease") { propertyToRemove = property; } // If the property's name is "OutputPath", change its value // from "bin\debug\" to "bin\release\". if (property.Name == "OutputPath") { property.Value = @"bin\release\"; } } // Remove the property named "RemoveThisPropertyPlease" from the // PropertyGroup if (propertyToRemove != null) { pg.RemoveProperty(propertyToRemove); } // For each PropertyGroup that we found, add to the end of it // a new property called "MyNewProperty". pg.AddNewProperty("MyNewProperty", "MyNewValue"); } // The project now looks like this: // // <?xml version="1.0" encoding="utf-16"?> // <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> // <PropertyGroup> // <Optimize>true</Optimize> // <WarningLevel>4</WarningLevel> // <MyNewProperty>MyNewValue</MyNewProperty> // </PropertyGroup> // <PropertyGroup> // <OutputPath>bin\release</OutputPath> // <MyNewProperty>MyNewValue</MyNewProperty> // </PropertyGroup> // </Project> Console.WriteLine(project.Xml); } } }
