<p>Demo for Pdb2Xml round-tripping</p>
<p><b>Overview</b>:</p>
<p>The Pdb2Xml tool can convert a pdb file into xml, allow you to edit the xml,
and then convert back to a pdb file.&nbsp; </p>
<p>Pdbs for managed code generally hold the source to IL mappings and the name
of the local variables. Pdbs can be created and viewed with the com-classic
<a href="http://msdnwiki.microsoft.com/en-us/mtpswiki/ms231034(VS.80).aspx">
CorSym APIs</a>. MDbg provides managed wrappers for these APIs in corapi\sym*.</p>
<p>This tool originally started with this
<a href="http://blogs.msdn.com/jmstall/archive/2005/08/25/pdb2xml.aspx">blog
entry</a> about converting Pdb to Xml, and then was expanded to
convert Xml back to Pdbs. </p>
<p>&nbsp;</p>
<p><b>Demo</b>:</p>
<p><b>1) Start with a simple test.cs file</b>:</p>
<pre>using System;
class MyTest
{
static void Main()
{
int myLocal = 5;
Console.WriteLine(&quot;Hi&quot;);
Console.WriteLine(&quot;Value:&quot; + myLocal);
}
}</pre>
<p><b>2) Compile it</b>.<br>
csc test.cs /debug+</p>
<p>This should produce both test.exe and test.pdb. </p>
<p><b>3) Run it under a debugger and we see</b>:</p>
<pre>mdbg&gt; run test.exe
STOP: Breakpoint Hit
6:{
[p#:0, t#:0] mdbg&gt; sh 10
1 using System;
2
3 class MyTest
4 {
5 static void Main()
6:*{
7 int myLocal = 5;
8 Console.WriteLine(&quot;Hi&quot;);
9 Console.WriteLine(&quot;Value:&quot; + myLocal);
10 }
[p#:0, t#:0] mdbg&gt; print
myLocal=0
[p#:0, t#:0] mdbg&gt;</pre>
<p>&nbsp;</p>
<p><b>4) Run the pdb2xml tool to convert the pdb to an xml file</b>.</p>
<pre>..\..\bin\Debug\pdb2xml.exe test.exe a.xml</pre>
<p>The xml file looks like:</p>

<p>We can now edit the XML file and convert it back to a pdb. First we'll just
rename the local:</p>

<p>This will update the executable image (test.exe)&nbsp; because an exe
contains a stamp for the pdb. When the pdb is changed, the exe's stamp must be
updated.</p>
<p><b>7) Now when we run under a debugger, we see the local is updated</b>.</p>
