c# - How to read cell values from existing excel file -

-

i want read each cell value in excel file, not able cell values after trying different examples in net. not getting result following code, can 1 on this. using .net framework 2.0

string filepath = "f:/bulktest.xlsx"; microsoft.office.interop.excel.application excelapp = new microsoft.office.interop.excel.application(); excelapp.visible = true; microsoft.office.interop.excel.workbook wb = excelapp.workbooks.open(filepath, missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value,missing.value);  microsoft.office.interop.excel.worksheet sh = (microsoft.office.interop.excel.worksheet)wb.sheets["sheet1"]; range excelrange = sh.usedrange;  (int i=2; i<= excelrange.count + 1 ; i++) {     string values = sh.cells[i,2].tostring(); }

till trying take cell values directly variables, try take cell values array using range. thanks!!!! – teja varma 13 mins ago

no. didn't mean :) mentioned in comment can store entire range in array. doesn't mean need loop though each cell store in array. can directly assign values of range array. see example.

xlrng = xlworksheet.get_range("a1", "a20");  object arr = xlrng.value;  foreach (object s in (array)arr) {     messagebox.show(s.tostring()); }

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
