如何在编写自定义任务时访问MSBuild的属性列表？

Question

我需要编写一个自定义任务来打印所有已定义的属性(非保留属性).所以在我的C#代码中,我想访问MSBuild引擎的属性列表,我不知道如何.请帮忙.

前面的示例将锁定您的项目文件.这可能会导致问题.例如,如果您在同一项目文件中多次调用该任务.这是改进的代码:

using System.Xml;
using Microsoft.Build.Evaluation;
using Microsoft.Build.Utilities;

namespace MSBuildTasks
{
    public class GetAllProperties : Task
    {
        public override bool Execute()
        {
            using(XmlReader projectFileReader = XmlReader.Create(BuildEngine.ProjectFileOfTaskNode))
            {
                Project project = new Project(projectFileReader);

                foreach(ProjectProperty property in project.AllEvaluatedProperties)
                {
                    if(property.IsEnvironmentProperty) continue;
                    if(property.IsGlobalProperty) continue;
                    if(property.IsReservedProperty) continue;

                    string propertyName = property.Name;
                    string propertyValue = property.EvaluatedValue;

                    // Do your stuff
                }

                return true;
            }
        }
    }
}

使用.NET 4：

using Microsoft.Build.Evaluation;
using Microsoft.Build.Utilities;

namespace MSBuildTasks
{
    public class GetAllProperties : Task
    {
        public override bool Execute()
        {
            Project project = new Project(BuildEngine.ProjectFileOfTaskNode);
            foreach(ProjectProperty evaluatedProperty in project.AllEvaluatedProperties)
            {
                if(!evaluatedProperty.IsEnvironmentProperty &&
                    !evaluatedProperty.IsGlobalProperty &&
                    !evaluatedProperty.IsReservedProperty)
                {
                    string name = evaluatedProperty.Name;
                    string value = evaluatedProperty.EvaluatedValue;
                }

                // Do your stuff
            }

            return true;
        }
    }
}
