区分正在运行的 VS 实例的唯一方法是通过它们已加载的解决方案来选择它们。幸运的是(不是运气),VS 还在运行对象表中公开了 EnvDTE.Solution 对象。您可以使用Roman 的 RotView-Win32.exe 实用程序来查看它的外观。
一些迭代 ROT 并返回所有活动解决方案的示例代码:
using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.ComTypes;
public class VSSolution {
public string Name { get; set; }
public EnvDTE.Solution Solution { get; set; }
}
public static class VSAutomation {
public static List<VSSolution> GetRunningSolutions() {
var instances = new List<VSSolution>();
// Get running object table reference iterator
IRunningObjectTable Rot;
int hr = GetRunningObjectTable(0, out Rot);
if (hr < 0) throw new COMException("No rot?", hr);
IEnumMoniker monikerEnumerator;
Rot.EnumRunning(out monikerEnumerator);
// And iterate
IntPtr pNumFetched = new IntPtr();
IMoniker[] monikers = new IMoniker[1];
while (monikerEnumerator.Next(1, monikers, pNumFetched) == 0) {
IBindCtx bindCtx;
int hr2 = CreateBindCtx(0, out bindCtx);
if (hr < 0) continue;
// Check if display ends with ".sln"
string displayName;
monikers[0].GetDisplayName(bindCtx, null, out displayName);
if (displayName.EndsWith(".sln", StringComparison.CurrentCultureIgnoreCase)) {
object obj;
Rot.GetObject(monikers[0], out obj);
if (obj is EnvDTE.Solution) {
instances.Add(new VSSolution { Name = displayName, Solution = (EnvDTE.Solution)obj });
}
else Marshal.ReleaseComObject(obj);
}
}
return instances;
}
[DllImport("ole32.dll")]
private static extern int CreateBindCtx(uint reserved, out IBindCtx ppbc);
[DllImport("ole32.dll")]
private static extern int GetRunningObjectTable(int reserved, out IRunningObjectTable prot);
}
经测试的示例用法:
foreach (var sln in GetRunningSolutions()) {
if (sln.Name.EndsWith("ConsoleApplication1.sln")) {
var dte = sln.Solution.DTE;
// etc...
}
}
