Test value fist character of string - C# [duplicate]

Question

in one of our templates for report printing there is the following code:

 if (!string.IsNullOrEmpty(assetModel.Belongings)) { description = string.Format("{0}{1}{2}", description, string.IsNullOrEmpty(description) ? "" : ", ", assetModel.Belongings); }

I would like to test the first character of the Belongings field. if it IS NOT a "," then the code above should be used but if it IS a "," the code should be like:

 if (!string.IsNullOrEmpty(assetModel.Belongings)) { description = string.Format("{0}{1}{2}", description, string.IsNullOrEmpty(description) ? "" : "", assetModel.Belongings); }

Please help, how can I test this value of the first character?

you can use String.StartsWith

Method StartsWith is self-explaining:

if (description.StarstWith(",")) { //... }

thanks, this is the solution I was looking for, and this is the result. Sorry, can't get the code shown in the right way. if (!string.IsNullOrEmpty(assetModel.Belongings)) {if (assetModel.Belongings.StartsWith(",")) { description = string.Format("{0}{1}{2}", description, string.IsNullOrEmpty(description) ? "" : "", assetModel.Belongings); } else { description = string.Format("{0}{1}{2}", description, string.IsNullOrEmpty(description) ? "" : ", ", assetModel.Belongings); } }

Use IndexOf to check if the index of the , character is 0, meaning it's at the start of the string.

if (description.IndexOf(',') == 0) { // description starts with a , }

It should work, but IndexOf isn't build for this purpose. In my optinion StartsWith() would be better in this context.

Searching whole string instead of just checking description[0]==','?

@Jannik true, didn't think of StartsWith until after I posted.

@Steve I feel you, I was about to post a substring-alternative, well, there are many different roads to reach the same goal.
