I am trying to post a json string via a form submission ( multi-part

  • 0

I am trying to post a json string via a form submission ( multi-part encoding ) to an aspx page and send back a response based on the deserialized json string. ( I really need to do this via a form submission. no ajax )

I dunno why this doesn’t work, but every time I try a simple string replacement to replace the single quotes with double quotes in the json string. It doesn’t seem to be happening.

Here’s a summary of what I did.

Here’s the JSON string,

[["\n 22.02 13:15 \n ","\n \n \n \n ","\n \n \n \n ","\n \n \n "," \n Vereina\n ","\n \n ","\n 35 000\n ","\n 24.03.11\n ","\n Taiwan \n ","\n \n ","\n \n "]]

To send it via form data I replace all the ” quotes with ‘ quotes like this,

[[‘\n 22.02 13:15 \n ‘,’\n \n \n \n ‘,’\n \n \n \n ‘,’\n \n \n ‘,’ \n Vereina\n ‘,’\n \n ‘,’\n 35 000\n ‘,’\n 24.03.11\n ‘,’\n Taiwan \n ‘,’\n \n ‘,’\n \n ‘]]

On the server side I am replacing the new lines since I don’t need them,

[[' 22.02 13:15 ',' ',' ',' ','  Vereina ',' ',' 35 000 ',' 24.03.11 ',' Taiwan  ','  ','  ']]

Then I use the C# string Replace method like this .Replace(“‘”,”\””) on the above, and what I get is

[[\" 22.02 13:15 \",\" \",\" \",\" \",\"  Vereina \",\" \",\" 35 000 \",\" 24.03.11 \",\" Taiwan  \",\"  \",\"  \"]]

I am observing this in the quick watch window of MS Visual Studio, also while debugging the code.

    The debugger shows strings as they would appear as C# string literals. That’s why quotation marks are escaped. The string is not affected, though.

    You can easily verify that by printing the string somewhere.

    Quick demonstration:

    enter image description here

    In the debugging windows (purple) the string shows with escaped quotes (and surrounded by quoation marks, thus making it a C# string literal), while the output in the console (red) shows the actual contents.
