What's the equivalent of VB's Asc() and Chr() functions in C#?
(12 answers)
Closed 8 years ago.
I have this code:
Dim sCenter As String
sCenter = Chr(27) + Chr(97) + Chr(1)
And I'm trying to convert to a C# code. Online converters always fail to convert... :(
So, what is the C# equivalente of Chr(number)?
Maybe Char.ConvertFromUtf32(10);
Feel like taking risk to answer but how about?
string sCenter;
sCenter = "" + (char)27 + (char)97 + (char)1;
Thanks to James Curran's comment about char integral addition. As his suggested, I added meaningless "" with char to get string + char which uses .ToString() with String.Concat method at background.

How do I interpolate strings?

Closed 5 years ago.
HttpResponseMessage response = await client.PutAsJsonAsync($"api/products/{product.Id}", product);
In the above code I've been using the $ keyword but I don't the significance of this keyword. I searched in google but coiuldn't find proper answer. I think this might be a duplicate but couldn't find relative answer even in stackexchange.
Thanks in advance
It's an interpolated string - the new feature of C# 6, which is basically just a syntax sugar for String.Format (compiler converts interpolated strings into the String.Format calls). Your string is equivalent to
String.Format("api/products/{0}", product.Id)
$"api/products/{product.Id}"
is the short version for
string.Format("api/products/{0}", product.Id);
You could have a look in the MSDN

How to replace straight quotation mark (")

Some string variables have a " in the data which recks with my php code. I want to take it out in my C# code before the data gets passed to php. I just can't remember the way of doing it, but I tried with this :
line.Replace(#""", "");
This is not correct in Xamarin, what is the good syntax?
I guess this would work.
line.replace("\"","");
use \ to escape it.
line.Replace("\"", "");

Why is !0 a type in Microsoft Intermediate Language (MSIL)?
(2 answers)
Closed 6 years ago.
What the meaning of " (!0) " in ILNumerics just like this
return (!0)ILMathInternal.exp(this.m_mu);
and like this,
return 0.5 + (!0)ILMathInternal.log(this.m_sigma) + this.m_mu + (!0)ILMathInternal.log(ILMathInternal.sqrt(2.0 * ILMathInternal.pi));
Why we use this kind of expression---"(!0)" ?
(!0) has no meaning, it is not valid C#
If I had to guess, which I do, I suspect the (!0) is how a decompiler has chosen to represent some IL code that has no C# representation.

Remove or Convert ' to (')

I found a similar question on how to decode ^#39; or simply ' in php, but I have been having trouble finding a way of decoding that value in c#. Thoughts? I have been trying the following in my code...
agenda.MeetingLocation = agenda.MeetingLocation.Replace("'", "''")
However, the value in my form field is John Doe's test. The value I see for agenda.MeetingLocation is:
John Doe's test
(the ^ is a &)
This should work if it's encoded like "& #39;" instead of "^#39;". Are you sure your input uses "^"?
System.Web.HttpUtility.HtmlDecode("John Doe's test.");

With block equivalent in C#?
(19 answers)
Closed 9 years ago.
I am trying to convert simple vba "with statemnt" to C#. ProductRangeA and B are named ranges. Could someone to give a hint?
With ProductRangeA
myRow= .Rows.Count:
myValue= .Value
End With
With ProductRangeB
myRow= .Columns.Count:
myValue= .Value
End With
As HighCore said, there's no C# equivalent to VB's With block. Here's the equivalent C# code:
myRow = ProductRangeA.Rows.Count;
myValue = ProductRangeA.Value;
myRow = ProductRangeB.Columns.Count;
myValue = ProductRangeB.Value;
Since you can't avoid typing ProductRangeA and ProductRangeB twice each, you can reduce typing by using shorter variable names. That can make the code more difficult to understand, of course.
