Each application should have an uninstall command that you can run. It will be located in the registry. Here is a Stack Overflow question that will give you the details on how to do it exactly:

Once you know how to do this, it is simply a matter of writing the C# code to make that command line call.

在您的按钮click事件中，使用以下代码:
一个警告:在32位操作系统中，代码可以按原样使用，但在64位操作系统中，
您必须将目标CPU"设置为x86(而不是AnyCPU).

In Your button click event use the below code:
One Caveat: In 32-bit os, the code can be used as it is but in a 64-bit os,
you have to set the ''Target CPU'' to x86 (instead of AnyCPU).

RegistryKey rgKey = Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall");
        ProcessStartInfo info = new ProcessStartInfo();
        Process uninstallProcess = new Process();
        var ns = rgKey.GetSubKeyNames().Where(n => n.ToLower().Contains("cricket"));
        if(ns.Count() > 0)
        {
        foreach (var vsKey in rgKey.GetSubKeyNames())
        {
            RegistryKey productKey = rgKey.OpenSubKey(vsKey);
            string dispName = Convert.ToString(productKey.GetValue("DisplayName"));
            string uninstlString = Convert.ToString(productKey.GetValue("UninstallString"));

            if (dispName.ToLower().Contains("cricket")) //Put the name of the Application you want to uninstall here
            {
                string prdctId = uninstlString.Substring((uninstlString.IndexOf("{")));
                uninstallProcess.StartInfo.FileName = "MsiExec.exe";
                uninstallProcess.StartInfo.Arguments = " /x " + prdctId + " /Qn";
                uninstallProcess.Start();
                break;
            }
        }
       }
