Because <a href="https://msdn.microsoft.com/en-us/library/8kb3ddd4%28v=vs.110%29.aspx#M_Specifier" rel="nofollow"><code>M</code> format specifier</a> meaning is single digit month number from <code>1</code> to <code>12</code> and <a href="https://msdn.microsoft.com/en-us/library/8kb3ddd4%28v=vs.110%29.aspx#gSpecifier" rel="nofollow"><code>g</code> specifier</a> means period or era such as <code>A.D.</code>

Since other characters doesn't referring any format specifiers, they reflected to the output exactly what they are.

By the way, your code seems little bit complicated and buggy. First, you generate a format with using <code>ShortMonthFormat</code> and <code>ToShortDateString</code> and then generate string representation of your <code>DateTime</code> with that formatted string.

That's why your code looks like;

<pre><code>string result = dtc.ToString("ddd, 27-Mar-16");
</code></pre>

which does not too much sense.

You can fix your code to use your <a href="https://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.shortdatepattern" rel="nofollow"><code>ShortDatePattern</code> property</a> of your <code>CurrentCulture</code> instead of you use <code>dtc.ToShortDateString()</code> like;

<pre><code>string result = dtc.ToString(string.Format("{0}, {1}", 
 ShortMonthFormat, 
 CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern));
</code></pre>

By the way, based on variable name (which is <code>ShortMonthFormat</code>), <a href="https://msdn.microsoft.com/en-us/library/8kb3ddd4%28v=vs.110%29.aspx#dddSpecifier" rel="nofollow"><code>ddd</code> specifier</a> is for abbreviated day names. If you wanna get abbreviated month names, you can use <a href="https://msdn.microsoft.com/en-us/library/8kb3ddd4%28v=vs.110%29.aspx#MMM_Specifier" rel="nofollow"><code>MMM</code> specifier</a> instead.

<pre><code>string ShortMonthFormat = "MMM";
</code></pre>

blocks|key|2941946|text|似乎您的代码中有一个bug。您正在尝试获取短日期格式，但不是获取格式，而是格式化日期，这将导致格式化日期而不是格式。您可以在代码中修复这个问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2941947|string+format+=+string.Format(

++CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern

It seems that you have a bug in your code. You are trying to get the short date format but instead of getting the format you format the date which will result in a formatted date and not the format. You can fix this in your code:

<pre><code>string format = string.Format(
 "{0}, {1}",
 ShortMonthFormat,
 CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern
);
string result = dtc.ToString(format);
</code></pre>

You have not specified a <code>CultureInfo</code> so <code>CultureInfo.CurrentCulture</code> is used which is reflected in <code>CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern</code>. If you want to use another <code>CultureInfo</code> you will also have to use it in <code>dtc.ToString(format, cultureInfo)</code>.

Another way to explain the fix is that you have to replace <code>dtc.ToShortDateString()</code> with <code>CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern</code>.

I have a simple program which will return the Day and the ShortDate. For example, if the input is 27th March 2016, the output will be "Sun, 03/27/2016"

<pre><code>string ShortMonthFormat = "ddd";
DateTime dtc = Convert.ToDateTime("2016-03-27 12:26:41.210");
string result = dtc.ToString(string.Format("{0}, {1}", ShortMonthFormat, dtc.ToShortDateString()));
Console.WriteLine(result);
Console.ReadLine();
</code></pre>

This code works for the current system Date format which is <code>MM/dd/yyyy</code>(03/27/2016). But if the system's Date format is changed to <code>dd-MMM-yy</code>(27-Mar-16), the code is returning the following output <code>"Sun, 27-3ar-16"</code>

Mar(March) is returned as <code>"3ar"</code>

Aug(August) becomes <code>"AuA.D."</code>
